apt-cacher in main + apt-zeroconf

[Kevin Fries]

There is another problem with apt-zeroconf... it relies on Avahi.  Avahi
has lots of environments that it does not work in.  In my office, the
machines are not seeing each other.  When we had a meeting at the Google
(Sketchup) offices in Boulder, Avahi did not work correctly their
either.  I don't think its a bug in the software, but instead it has to
do with the way the routers are set up.

Before turning on anything like that, you would need to insure that it
would be reliable.  That is why I proposed the "scan" technique.  If the
scan fails, either due to protocol issues or the fact that there is no
server, it fails over to the old way.

@Fabian: I agree with you to a point.  Auto-detection can be
problematic.  But I suggest auto-detection like compiz auto-detects.  If
its not there, don't force it.  Or even better yet... set up the always
works version, but if I can reliably detect a better way, reconfigure to
that better way by default.  Decreasing bandwidth without having to
remembering to configure every new client is one of those features that
make good buzwords with IT managers.  Canonical has made statements
indicating that they want to go after the corporate desktop... this is
exactly the type of feature that plays well with that demographic.
