	It sounds like it'd be cheaper and allow you to make better use of  
cache, so I'd assume it's good.

	Being able to rely on a cache will impact your design and will  
generally be good.  I do some things very similar to this that  
involve grabbing some list-like data, and then fetching items related  
to items within the list.  As many as I can get come from cache, and  
the rest have to be fetched from the source, and then placed back  
into the cache.
