Amazingly, yes.

Well, that's certainly not the current use-case.

The problem they're trying to solve is where you have a number of
people and/or vehicles that are moving about, and you want structured
conversations between them, and some of these vehicles have uplinks to
a stable network. So there are gateways between XEP-0174 and S2S
floating about too.

My understanding is that it's working quite well, experimentally. But
really I'd be surprised.
