[Twisted-Python] Twisted web proxy

I'm trying to implement a simple web proxy using Twisted. With 3 or 4 web-based 
apps on my machine (moin, roundup, PyDS, ...) I'd like to put them all behind a 
single server on port 80, for ease of access. I could install Apache and use 
ProxyPass[Reverse], something like this:

    ProxyPass         /moin/ http://localhost:8081/
    ProxyPassReverse  /moin/ http://localhost:8081/

    ProxyPass         /roundup/ http://localhost:8082/
    ProxyPassReverse  /roundup/ http://localhost:8082/

But that seems fairly heavyweight. I tried looking at proxy.py in the Twisted 
examples, and it sort-of does what I'm after, but seems to give inconsistent 
results (some proxied pages just don't appear), and the sample code doesn't log 
anything I can scan for problems (and I can't get it to - wherever I put the 
print statements seems to be wrong :-() I suspect that I'm mucking up attaching 
children (the example just proxies everything from the root, I want to hang the 
remote server "lower" in the tree), but I can't see how.

Has anyone got any code that does this sort of thing, that they'd be willing to
