5. Sharing all - Mikogo

This is another one of those sites that seems to offer all the necessary support mechanisms you could imagine. Among the capacities listed on their website for PCs (more restricted for Macs) are:

• Screen Sharing
• Switch Presenters
• Remote Control
• File Transfer
• Meeting Scheduler
• Recording & Playback
• Whiteboard
• Voice Conferencing service

I have yet to put it through its paces, but clearly these types of activities are rapidly becoming mainstream.
