How to setup screen sharing for business meetings? I'm wondering if it would be possible to use android-based tablets (or ipads) in business meetings.

The idea would be to have each person in the meeting, with its individual tablet, see what a "meeting-leader" is seeing on his own tablet, navigating through the web or using apps.

I see some solutions that seem to be mostly directed into remote-control, but what I want is just to screencast in realtime to multiple receivers, privately. The ability to let some other person take control would also be nice, but not mandatory.

How could I set this up?
You may use join.me for this. The organizer installs the client on his/ her machine and rest everyone may join in through their web browser.
