named cache "zones"

[Garth Patil]

hi,
i've just started using memcached with the java api (thanks greg!), and i've 
looked around the archives for an answer to this question, but haven't been 
able to find it.
is there a way to create multiple named caches within a single memcached 
process?
for example, i'd like to have a few caches that have potentially overlapping 
keys, but all stored in the same memcached instance. other than just 
concatenating the cache name to the key, is there a good way to do this in 
memcached?
thanks,
