The current profiles implementation do, but do we really need them? Are things 
like the description, display name etc really necessary for the profile? Can 
we move these out somehow?

Isn't the whole point of profiles to abstract away any CM's particular 
features and thus stop a client from having "blessed" CMs?

This shouldn't be in the profile imho.

I propose we simply have a "supports-secure-connection" capability and let the 
client decide on policy (and inform the user etc).

I have no idea what the split-account and contact-search capabilities mean. So 
far I've decided to use the following capabilities (incomplete):


Avatars can be determined by looking at which interfaces the CM exports. Is it 
really necessary to have this in the capabilities?

Can anyone think of any additional capabilities which should be added?

I agree with this path.
