well there are two features about my project i want to discuss n how to go about it !

1) i want to make different versions of my application n update user automatically, just like yahoo,msn messengers that when their new version is updated the user automatically gets notified

2) i want to make my setup file usable by only one user/machine, other persons should download their own copy.

in case if ne one is interested in finding out wat my project is about then visit this thread
