So... any opinions on whether or not to try to keep fanout in CAP ? John? Anybody?

Having just reread the fanout section in the I-D, I'd say cut it. It doesn't introduce any truly new capabilities, and it does introduce some potentially serious security problems. Either the servers trust each other, or the server doing fanout has to be able to exercise the user's credentials on the remote server. Either way, it permits an attacker who subverts one server to use it against other servers, instead of limiting the damage to a single server.
