Quick Screen Share

About QuickScreenShare.com:

QuickScreenShare.com is the simplest way to share screens with anybody:

• No registration required and completely free.
• Nothing to install for sharer or sharee.
• Works on Windows, Mac, and Linux.
• Even lets you remotely control mouse and keyboard!

This free service is a side project from the creators of Screencast-O-Matic.com and is still in BETA. We use it extensively for remote user support and collaboration. The current version creates a direct peer-to-peer connection, so if you're on a super duper secure school or company network it may or may not be able to connect, but in most cases you'll find it works quite well so give it a shot!
