Yes, S5B is totally busted with MUC JIDs. We mostly brushed this off, saying
that you have to use real JIDs. I think it is not unreasonable to require
using real JIDs for a P2P connection, if only we had a better way of
communicating the JIDs (e.g. trading them in the file transfer exchange,
rather than requiring a non-anonymous MUC).

You mean the target is never informed.

Do we have to require their use? Is there a harm in using real JIDs even if
both peers are in a MUC? I don't think this needs to be specified.

This may be fine, but, does it open up any security issues? People hijacking
proxy connections by spoofing initiator JIDs?

I'd have to think more about this, but maybe it's fine.
Of course, your modifications would have to be optional extensions, to ensure
