nv/vat & CUCM, and firewalls

Hi guys...

I heard a lot of CU-SeeMe, so I decided I want to try it. However, two
problems exist:

1. We don't have PC's or Mac's connected to our net (I'm at SGI).
2. We are behind our filewall.

I read some blurb in some web page about being able to use nv/vat to
send/receive CU-SeeMe streams, and I am curious to try it. Our firewall
is configured to allow mbone traffic to go through, so it's easier to
go through our firewall with multicast than it is with standard IP unicast.
(the firewalls does not allow any useful point-to-point tcp/ip connectivity)

I got the 4.0b3 version of reflect and I was able to transmit some
video from nv that reflect understood (refmon's who command marks it as
NV MULTICAST, but not as a sender)

I am wondering if it is possible to enjoy the joy of CU-SeeMe, given the
above limitations.
