That sounds like any work I do here will help...

I don't know paste.deploy and I don't have time or inclination to learn 
it. However, any work I do will be aiming to make it simpler to slot in 
different bits in different roles. What does paste.deploy do?

I was toying with the idea of trying to have an IConfiguration utility 
such that ZConfig could be switched out, is that what you're talking about?

Indeed.

Well, I'll try and make this code encapsulated...

Yay! More config files, just what we need ;-)

How about just making an IApplication utility, or is IApplication too 
specific?

Yeah, this is exactly what I'm after :-)
