Odd. If MBone native tools aren't going to be offered, can
you please make sure source code is available for the player?
I normally use vat/sdr/rat on Digital Unix for watching NANOG,
and it seems RealNetworks, Inc. haven't figured out how to
compile their source on that platform yet. :-(
Have we sunk to proprietary, closed protocols for NANOG? 'Tis
a sad, sad day. :-(

As a representative of RealNetworks, do you have any comments
on the availability of source code to your player, for those
of us with multicast-supported systems you have chosen to
ignore? Or is it simply time to declare NANOG yet another
bastion of closed minds, and closed protocols?
