Conference desktop sharing software

I am looking for a completed solution that allows a user to set up multiple conferences that will allow desktop sharing and control. I would like the desktop sharing to be as close to TightVNC ([login to view URL]) as possible. I will need the client side solution to support an application and web(Java). I would like something that has been written in C++ if possible. I am then interested in other features. If you have code that already does this please submit a demo version with some documentation along with a price. If you would like to write the code that does this let me know how long it will take you and what features you can add. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Windows, Web
