Or you can do what was suggested in the list (don't know if it is
mentioned in the spec): cache the information about {client_name,
client_version} => caps* only after you receive the exact same
information from 5 or 6 different JIDs.
The roster is assumed to be for people you trust.
The cache should probably only cache after the same info is received from 5
or 6 different domains.
- Transports can pollute the cache easily because they often have well in
excess of 20 contacts subscribed
- Corporate installations probably only have one or two domains, but they
probably won't suffer from the lack of caching either.
