When we discussed this in Darmstadt, we decided to create a working
system as fast as possible by just broadcasting personal messages in
the same way as regular messages. Overhead, sure. But it can be
improved later. The same goes for user status messages, they will
be distributed the same way as normal channel messages. You can
store the message-id together with the user-information and this
way associate logoff-messages to logon-messages (for consistency).

Yes. But the user-side shouldn't be so hard to do. It is important to
get the network structure right.

Of course.
