Great! VNC over stream tubes could really be a killer feature in the
GNOME desktop.

First I suggest you to use latest Telepathy packages. As you're using
Ubuntu you can use our PPA. See

You don't have to patch VNC anymore. I needed to do it in [1] because
when I wrote this post we didn't have Inet Stream tubes yet, so I had to
use an Unix socket. We have them now, so you just have to export the
socket of your VNC server through a stream tube. Then on the other side
accept the tube as an Inet stream tube and connect your VNC client
(Vinagre I guess?) to its socket.

I already got this working using Vinagre and the tube test script
shipped with telepathy-python: tube-stream-muc.py.
You'll have to use HEAD version as the latest release still use Unix
sockets instead of Inet ones.

You could also be interested in my Empathy tube-demo branch.
http://git.collabora.co.uk/?p=user/cassidy/empathy.git;a=shortlog;h=tube-demo
I wrote it as a tubes integration proof of concept with Gtetrinet.

Tubes integration in the desktop is still an open question. I hope we'll
have something soon with the Mission Control next gen. We'll probably
use D-Bus invocation to launch the right application when we receive a
new incoming tube or something similar.

As a start maybe you could open an Empathy VNC branch based on my
tube-demo branch and add VNC support. Basically you have to do 2 things:
a) Handle incoming tubes which have "vnc" as service (as I do for
tetrinet).
b) Add a "Share my desktop" menu entry which launch a VNC server if
needed and export its socket trough a tube.


Let me know if you have others questions.


Regards,
