As to firewall configuration for Netmeeting:
To enable NetMeeting 3  multipoint data conferencing - program sharing,
Whiteboard, Chat, file transfer, and directory access- your firewall only
needs to pass through primary TCP connections on assigned ports. 
NetMeeting audio and video features require secondary TCP and UDP
connections on dynamically assigned ports. Therefore, if you establish
connections through firewalls that accept only primary TCP connections, you
will not be able to use the audio or video features of NetMeeting.

To establish outbound NetMeeting connections through a firewall, the
firewall must be configured to do the following:
*	Pass through primary TCP connections on ports 389, 522, 1503, 1720,
and 1731.
*	Pass through secondary TCP and UDP connections on dynamically
assigned ports (1024-65535).

As to simultaneous DTS connections: no idea.
