Nope, as it turns out, the request my HTTPTransport was sending was 
malformed. When the XMLRPC service URL was using the https scheme, it 
was making an SSL request on port 80 which was confusing the server. 
Once I changed my HTTPTransport to explicitly use port 443 in the URL 
given to urllib2, then it started working.

I've pushed this fix up to lp:~doxxx/brz/lp_proxy just now. I still need 
to figure out how to not clobber an explicit port in the XMLRPC service URL.

Ciao,
