Uh, no.

This only worked because of a bad design decision in tcp.py - it will not 
work in CVS or in any future release. The real solution then is to fix the 
pb connection APIs so they use pluggable transports. Glyph tends to do this 
using URLs, e.g. "pb-tcp://localhost:7777/bar" or "pb-unix://tmp/.socket" or 

There should hopefully be some solution in CVS soon, given that we need this 
functionality to run twistedmatrix.com.
