Just checking... Where is the ssid "mesh1" coming from? Are you changing
the ssid in ifcfg-wmesh0? Or are both active on the XS-on-XO at the same
time? Are you using an AA?

More or less, yes. What is happening is when sugar detects an adhoc
network it assumes that the network is link-local and never tries to use
dhcp to gain a network address. If you can switch over gnome and connect
to "school-mesh-0" you should see the network info has been supplied by
the dhcp server on the XS-XO. Once in sugar your back to using
169.254....
