Yes, I think this is what we want.  Although I thought we could
probably change screen's keyboard mapping such that C-] is the escape
character and at the same time finally get support for sending C-] to
the domain -- I keep getting stuck in nested xencons clients...
You can have screen -x as a login shell or run it from command= in a
.ssh/authorized_keys file.

I think it should be an option in the domain configuration file
whether the domain creating tool should also setup a screen session
backing the console.  I think this needs to be somehow linked to the
domain creation tool because otherwise you won't capture the entire
output.
If we support multiple consoles for a single domain, it would also be
nice to have them all connected to the same screen session, allowing
you to switch between the consoles using C-] 1, C-] 2, ...
