Conferencing Compatibility

[Edward Pillow]

Hello,
I'm trying to start a study group via. internet for online
college classes. It would be great to allow multiple
people to communicate with voice, chat, file sharing and
whiteboard. However, I have two major concerns / questions.

1) Can multiple share all of these features?
2) Can MSN Messenger w/ NetMeeting communicate with
Windows Messenger and share these applications?

Any insight would be appreciated. Also, any suggestions on
the conferencing methods would be appreciated.

Thanks,
Ed
