Thank you MYK!
I will test this at at that site tomorrow. If anyone is available after 1pm
EDT, in the NCSA Lobby I will try to test for at least four hours...most
likely using chat for communication:) This is actually a cool problem. Not
for production:( but as a puzzle:)
Anyone: (Opinion) Does it matter if I am testing this NATed site in the NCSA
Lobby or in a "room"...as one is dynamically multicasted and the rooms are
statically mulitcast addressed? Would the nature of a NATed site more prone
to showing video in either case than the other? ...okay I know I am drawing
straws now:)
Thanks all,
John
