I'd rather have non-duplicated keys, so I'd prefer


or some such. But I agree, this is an optimal use for caps:

However, as an optimization I think we can assume that all servers accept
RFC1436, so how about


Of course, the idea is that caps should be a wide-open interface and people
can use whatever keys they think are meaningful. At some point, however, like
MIME types we should publish a canonical list of widely recognized caps keys.

I should also publish a reference implementation of how to interpret a caps
file for interested client authors, though I think the file format is pretty
