I know that we can reverse engineers sites definitions and other sharepoint moss entities but can we take a workflow that has been created via the UI and reverse engineer it to a vs.net based workflow?

I am a totally blind college student who’s had several programming internships so my answer will be based off these. I use windows xp as my operating system and Jaws to read what appears on the screen to me in synthetic speech. For java programming I use eclipse, since it’s a fully featured IDE that is accessible.
In my experience as a general rule java programs that use SWT as the GUI toolkit are more accessible then programs that use Swing which is why I stay away from netbeans. For any .net programming I use visual studio 2005 since it was the standard version used at my internship and is very accessible using Jaws and a set of scripts that were developed to make things such as the form designer more accessible.
For C and C++ programming I use cygwin with gcc as my compiler and emacs or vim as my editor depending on what I need to do. A lot of my internship involved programming for Z/OS. I used an rlogin session through Cygwin to access the USS subsystem on the mainframe and C3270 as my 3270 emulator to access the ISPF portion of the mainframe.
I usually rely on synthetic speech but do have a Braille display. I find I usually work faster with speech but use the Braille display in situations where punctuation matters and gets complicated. Examples of this are if statements with lots of nested parenthesis’s and JCL where punctuation is incredibly important.
Update
I'm playing with Emacspeak under cygwin http://emacspeak.sourceforge.net I'm not sure if this will be usable as a programming editor since it appears to be somewhat unresponsive but I haven't looked at any of the configuration options yet.
You can't.
There are steps you can take to make it a little more difficult, but ultimately any executable on the local machine is crackable. Eventually, that code has to be converted into native machine code and every application that is runnable is vulnerable.
What you want to do is just make it difficult enough to crack to make it not worth peoples' trouble.
Some suggestions I have for you to help protect your application:
- Obfuscate your code. Dotfuscator has a free edition and comes with Visual Studio.
- Use public/private key or asymmetric encryption to generate your product licenses. This ensures that only you can generate your license codes. Even if your application is cracked, you can be sure that they won't be releasing a key generator for your application, because it is impossible to reverse the key generating algorithm.
- Use a third-party packer to pack your .NET executable into an encrypted Win32 wrapper application. Themida is one of the better ones. This stops people from reflecting your application in .NET Reflector and makes it a pain to unpack for reversing.
- Write your own custom packer. If the third-party packers are too expensive, consider writing your own. Sometimes custom packers can be very effective, because there aren't well published methods on how to unpack them. The tutorial How to write your own packer gives a ton of good information on writing your own Win32 packer.
Ultimately though, if people want your application cracked they will. Look at all the commercial software out there that has a vast amount of resources to protect their applications and yet they are cracked before the applications are even released to the public.
A skilled reverse engineer can fire up IDA-Pro and slice through your application like butter no matter what you do. A packed application can be unpacked and obfuscation only prevents it from making it a walk in the park. All your hard work with your complex license code can be undone with a single byte patch.
You just need to accept that there is a very real chance people are going to pirate your software. There are some people who are never going to pay for your application no matter what and these are the people you don't need to worry about.
There are however, many businesses out there who would never risk a lawsuit and happily buy software licenses and many computer users who either don't want to risk it, find it wrong or are not tech savvy enough to pirate. These are your true customers, and you should focus your efforts on providing them with a good user experience and ignore the people cracking your software.
I've had my application pirated before, and I took it as a personal affront. Here I was, a small-time developer, pouring my heart and soul into an application and these people had the gall to pirate from me?! They were taking money directly from my pocket!
I immediately added in a bunch of draconian DRM code and attempted to sabotage any person using an illegitimate or cracked copy. I should of course have been working on making my application better instead of trying to stop the inevitable. Not only that, but I was hurting my true customers will all these extra protections I was putting in.
After a long battle I realized I was fighting the tides and all this time wasted was for naught. I took out all the phone-home code except for the barebones license functions and never looked back.

Yes.
Each of the OOTB workflows in MOSS are acctually what you call "vs.net based workflows".
IE - the OOTB workflows are provisioned via features, which you can find the manifests for in 12Hive/Templates/Features.
Find the feature.xml for the workflow you want to reverse engineer and it will point you to the dll. You can use Reflector to then see inside the assembly.
On top of the VS workflow, all the OOTB workflows add .aspx initiation forms to the workflow. These forms collect the parameters (IE approver's email) that get passed into the workflow.
This should get you pretty far down your path.
