Bert can answer better than I, but I took a look yesterday after patching in a
quick hack to see what it would take to do it "right" and it's non-trivial.

The packetcache stores the entire composed packet and simply returns it.  To
deconstruct it and munge it would be quite a performance hit I'd imagine.

It is certainly possible to get the data returned randomly from the backends
(and I patched that in to my code yesterday), but that doesn't completely
solve the problem, allthough it would go a long way towards fixing the issues
brought up in this thread.  The data returned changes based on your cache's
timeout instead of on every request.

Thoughts?
