I was more thinking for a WMS implementation that had some caching 
support built in. Sounds like we have set up the convention to allow for 
this; but lack a proof of concept.

However the point is made - Andrea is correctly describing the existing 
implementations. While this is not what I expected I can certainly roll 
with it; now if only there was a good way to tell where the source WMS 
server is :-P

Thanks for answering my questions everyone.
