Canonical is using twisted all over the place.  When you push a bzr 
branch to Launchpad, for instance, you're hitting an SSH server written 
in Twisted that handles auth and writing to the filesystem.  Ubuntu 
One's cloud sync is entirely twisted (and is *the* reason that twisted 
is installed by default on all Ubuntu desktops).
