Well... I think it's the best design that can address the problem given
the existing situation, unless we make a seperate way of requesting chat
room channels with some extra info, which I think would suck. I'm not
too sold on the self handle changing when we fiddle around with a
property/interface, but I don't think there's much we can do about that,
short of generating a self handle per channel which is constant and
guaranteed not to ever be a valid room nick in that channel.

+1... what's the mechanism for nick changing though? SetAlias on the
channel self_handle, property tweaking, or another interface on the channel?
