Yes, we need this (not specifically for nicknames, but for PEP avatars and all sorts). Thankfully the MIX service has a presence sub and is in your roster, so has everything it needs to do PEP relaying on the anonmising JIDs (but we should still spec this).

Specifically on the topic of nicks, I think nick uniqueness in a channel is a generally useful thing so I’d be sad to lose it completely, but it also seems like a potentially reasonable config option for the channel, as with the nick fully detached from addressing in MIX there’s no interop reason for uniqueness.
