GoToMeeting like functionality

[Adam Vande More]

I have need of hosting a video presentation.  Is there anything compatible
FreeBSD in this area, or am I going to have to find an alternative laptop?
Something like a view-only VNC connection sharing will not work.  I need it
to be easy and fast for these viewers, all of which have likely never heard
of Linux let alone FreeBSD.
