The ? here is (s, ay):

SetAvatar('image/gif', ByteArray('GIF89...'))

I'm not sure how we should deal with conflicting avatar requirements on
the different CMs. Requiring Mission Control to perform image format
conversion and resampling seems somewhat out of scope...

To answer this one I suspect I'll need to make industrial quantities of tea,
read the vCard specifications and meditate for a while :-)

We can leave this out for the moment and add it to the spec at the same
time as I add a corresponding Connection interface (which I haven't
designed yet either).

Tell the UI designer "if RequestChannelWithAccount raises Disconnected,
pop up a dialog offering to connect a suitable account"?

This would require some way for the UI to find out which of our account(s)
would be suitable to talk to that account, though...

This doesn't sound like it needs to be the same module as MC, really.
