Michail is choosing a method, which will be used by NM and should be
used by other laptop tasks as well.  It will almost certainly not be  
SSID based.

However, I have to question what is going on here ?
Why do I have to be on the school mesh to backup ?
If you can contact the backup server specified in
/home/olpc/.sugar/default/config, and it's host key
hasn't changed, you should backup.   Right ?

This might be the school server, or it might be a different
server ('cause Moodle is hogging all the resources on
the primary school server :-)
