Windows Meeting Space

Vista is supposed to have a major upgrade to NetMeeting called Windows Meeting Space. It supposedly has a more professional appearing interface. With WMS, you can have meetings with up to ten participants, where you can share your desktop or applications, connect to a network projector to view presentations, and pass notes privately to other participants. You can even distribute documents as handouts, and any participant can edit them with the changes automatically propagated to each particpant's copy (while leaving the original unchanged). Unfortunately, it can't be installed on pre-Vista operating systems, as it depends on Vista's People Near Me peer-to-peer networking functionality and uses IPv6, which is installed and enabled by default in Vista. But it's an easy, cost effective way to conduct small virtual meetings. Check out more on it here.
