It's a protocol, not an application. I actually thought of it in
relation to GoogleTalk (or whatever it is caled thse days - not sure),
but Google seem to have dropped server-to-server XMPP so you need a
Google account, and I suspect it is not realistic with just a dumb
phone.

If development of an XMPP app for dumb and feature phones (and
deployment of server infrastructure?) is acceptable - how many different
models would you need to support? is it feasible to have an SMS/XMPP
gateway with the required functionality? - then I suppose it can be
hooked to an existing PC/Smartphone infrastructure. I don't know of any
dumb phone chat facilities except SMS, which is really not a
person-to-person-to-group IM.

I think the OP clarified that one-to-one messaging was a requirement -
this is why Twitter is no good.

Can one get really cheap (surplus? used?) Blackberries today? They come
with messaging out of the box...
