Imo there are many ways for achieving this, some of which being easy,
other more difficult. The freedom you'll have in your design depends
on some variables:

- You'll anyway have to use a signalling protocol (e.g. RTSP, SIP,
XMPP, etc..) to make it working, so you'll have to carefully pick the
one which better suits your requirements (e.g. RTSP is pretty well
supported from GStreamer from both sides, for SIP or XMPP I suggest
you to give a look to the telepathy framework).

- Are you planning to make it compatible with standard clients? If
yes, which protocols do they use? If not, are you planning to write
the client application as well?

- Do you have resource constraints (network bandwidth, CPU, disk, memory)?

- Is it possible that multiple clients will connect to the same server?

If you can clarify the points of above it would be possible to give
you, in turn, an appropriate answer.
