Get specific guild by name/id

Would be nice if it would be possible to get get the informations about a specific guild by guild id and/or name from the guilds API.
Atm. this requires to fetch the whole list. This is slow, creates server load, uses bandwith and not needed in most of the cases (at least I think so :)).
Okay, it's possible for the developer to fetch the list once, cache the XML and query that cache, but I think the API should be able to do that (the server already holds a cache...).
