Re: (#489) Re: (#484) Speakfreely patches

Bob,

I rewrote the most recent SF (windoze) version to add a PTT flag embedded in
the normal audio packet stream. This allows a conference reflector to pass
PTT flags to all conference members automatically.  I also added logic to
prevent conference members from "doubling" or talking over the top of
someone else.  Duplex audio works ok in a 1:1 connection, but it really
kills conferences.

The only problem with my modifications is that it breaks SF.  Non-modified
SF clients can't communicate with my modified clients.

You are correct in your assessment of the old SF/PTT version.  It used a
separate UDP socket to exchange "PTT packets" with a single remote client.
This will not work in a conference.
