Well, the thing about stream tubes is that it works basically just
like SSH forwarding. It took me a while to recognize it, but now it's
So after setting up the tube you simply have a socket connection and
you can use that just like you would do in any TCP-base application.
In fact, Etoys simply reuses its "old" pre-Sugar collaboration code
with stream tubes.
