+1 for name space support.

We hacked in pseudo-namespace support into our client-side layer on  
top of the python client:

	terseListingCache = caches.MemCache(prefix='terse_listing_', seconds=0)

Being able to better support this commonly-used construct, and  
possibly the ability to expire all cached entries given a namespace  
name would be most helpful.
