I also have the same request. We have two RemoteRig (TS-480) installations
with nine users each, they would like the possibility to listen in.
In one of the locations, there is a PC running 24/7. We installed a normal audio
splitter cable and ran the second line to the PC's sound card input. We found
that using Teamspeak was better than Skype, since it is a permanent "room"
where you can log-on and listen.
The second location is PC-less, using only serial port forwarding (Lantronix). There
we still need a solution, which we would also use at the first location if possible.
