Right, but correct me if I'm wrong, my understanding is that URL stands 
for Univeral Resource Locator and URLs can encode all of the things you 
describe. They certainly contain the host and port, so shouldn't there 
be a graceful way to specify a URL once and have everything that needs 
that info or a subset of it get it from there?

(This isn't necessarily aimed at AutoBahn, seems to be something common 
in Twisted...)
