Perhaps the map parameters could actually be the key.  It could be
specified in the "src" attribute of the "img" tag without an extra
round trip to step to fetch a key.  If the key has not been seen
previously, render & cache the tiles.  If the key has been seen
previously, deliver tiles out of the cache.  If two users happen to
request identical map parameters, use the same tiles without different
keys.  Periodically, purge unused tiles from the cache.

Google's "mapsdt" & OGC's WMS servers are very convenient from a
developer's perspective.
