They won't even let you create a separate DLL that resides on the client machine? DAMN!

Do they want a Windows app or not?? They (and unfortunately, you too) will soon find out how costly it will be to find and fix bugs and update the application.......

If you have a team of developers, everybody must know everything about the app, instead of having different developers specialize on a certain logical tier. Database access methods is of no concern to the UI developer, the UI developer only cares that he is getting the objects he needs, he does not have to worry about HOW he is getting them....

My prayers are with you! (and I'm not even religious!)
