It could happen - we fit most of the IMPP requirements, except for
acknoledgement of message receipt, and security.

I cannot speak for everyone here, so I would speak for myself and
acknowledge that this may not be what the majority of the core developers
think. Jabber has several design goals - being built on XML technology,
extensible through that same XML, and to do all required communications
over a single connection from client to server. Beyond that, it would
appear one of the design goals is to make writing a client as simple as
possible - after you support the core protocol you can use it to talk to
any type of user, with extensions to the core (such as the ability to list
agent gateways) also being simple to implement.

If some major innovation comes out of the IMPP group which fits these
goals, then great - I imagine it will be absorbed even if it requires
changes to the protocol. However, if there is a change that goes against
this - for example using a binary data format, UDP packets, or extreme
complexity - it will probably not be absorbed and will become a transport.
