We are looking for a cross-compatible Mac/Windows Screen-sharing application. This is for a classroom where students will be able to view their professors screen through our website (Multiple students should be able to view this). Essentially I'd like to have app developed individually for Mac/Windows where it would display the users screen to multiple viewers on a website.
The process would be like this,
1. The professor would download the app (Compatible to both Mac/Windows)
2. Choose his screensize
3. Stream his screen live to our website
