Does anyone know if/when this will happen
as described in the help for Build 123?

"Firewalls and proxy servers will prevent you from
being fully able to use the current versions of
Active Worlds Browser. In particular, you probably
won't be able to see other people communicating with
you, and they won't hear you either. You might not
even be able to connect, in which case you will be
in Standalone Mode. We are working on a version that
will be able to function properly even when you are
using a proxy server, but in the meantime try to get
your system administrator to route you around the
firewall somehow (see the aworld.ini file for
specific port information)."
