<< You can set it up with Exchange Server >>
By that, she means that you can set up Exchange Conferencing Server for NetMeeting...this allows you to to have multi-point A/V as well as multipoint app sharing/chat/whiteboard, etc. W2K Advanced Server will also allow you to create your own internal ILS server for NetMeeting for easy-squeezy connectivity. But the bottom line is that you *can* use the chat function in NM without having to access the Passport servers. Plus, even without ECS, NM allows more than six people at a time to communicate via the chat feature, app sharing...anything that is data-only (Messenger allows a max of six, I believe...)
