my SMTP is up again :-)

I see some clear problems in my current proposal, but am not really keen
on fixing them, if I have not heard anything from you, yet. I would like
to get constant feedback.
Anyway, I have some new ideas and questions as well.

New ideas:
- No need for a groupchat to be a contact. We can simply change the
roster_window not to believe it is a contact. We can hardcode at GUI
level that all groupchats go to "Groupchats" group.
- Allow contacts to be actors: contact.unsubscribe()

- Bct, do "sessions" fit into the proposal? 
- When is the Plugin branch expected to be merged?
- When is the BOSH branch expected to be merged?

Recently, I have talked to bct and transferred some our ideas into code.
Like the class diagrams, also the code is just a 15 minutes job.

Best Regards,
