Hi folks,

I've committed the patch for same port operation ( Try to match source
port to dest port before using ephemeral source port) to the SUMOVER
vic - it now also includes the Tcl noMulticastBind resource to allow
for not joining the multicast group - so vic would only send video and
not receive - useful in low bandwidth situations.
