Have means to know if somebody is present
As an xmpp user, I would like to know if IRC users I want to talk to are present, so I don't get a message back from the server saying they're not.
At the moment the one way I know of is to manually
WHOIS said users.
- Have biboumi send presence updates. I assume biboumi can't possibly send presence updates for every single users on the server, it wouldn't know what users in the first place, and if it did it would probably be a huge number of users. Maybe only send presence for users that I ever talked to, or users I sent a presence subscription for.
- Maybe something can be done with chatstates/markers?
