You can Tunnel Sametime v2.0 through HTTP. This reduces the number of ports
needed for full application use to two. The A/V functions still require a
separate port. Depending on the firewall, you should be able to allow only
outbound traffic on ports 80 and A/V port. The return connection will be
allowed based on the established connection paradigm (If you request it,
you must want it.) Never forget, no system is 100% secure, but there are
tons of ways to mitigate the risks involved in doing your daily business.

Any application you use will potentially make you vulnerable to exploits
being sent to that application/port which is opened up in the firewall. So
that is why you need to be careful on exactly what applications get used on
your LAN. If you open up a certain port, you run the risk of unintended
traffic coming into your network through that port. Firewalls themselves
cannot distinguish between bad traffic and good traffic going through a
port you opened up. That's where getting some form of IDS on your network
will help you ensure only good traffic is coming/going through your LAN.

Doesn't Netmeeting behind firewalls still make the clients vulnerable to
exploits?

Lotus Sametime.. But you incur the expense of a Domino license. I've
also had good success with Netmeeting with both parties being behind
firewalls.
