That's pretty cool, but this whole mapping thing seems broken. Would
there be a way for a server to probe another server over the clearnet
for an onion address, then it can cache that and build it's own list? I
don't know a ton about the actual XMPP wire protocol so I'm not sure how
best to go about that, but it seems like something that could be done.
