For similar reasons I've been considering various affinity approaches
lately.  Most people are familiar with session affinity, but I'm
thinking of something more like "data" affinity.

Instead of having a big cache that is shared in order to increase the
chance of a request's data being in the cache, you would instead have
many smaller caches (just like ZEO works now) and send the requests to
the process(es) that are most likely to have the appropriate data in
their cache.
