Been thinking about this subject recently as I started messing with GPRS
 connections on FSO. Network management on the FR is one thing, but
adding a connected device is a mental mess, (for me anyhow). If I'm
connected, via a USB cable, to an eeePC then sometimes I want the eeePC
to be my router and forward from the FR to the world via its Network
connection and sometimes I want to use the FR as a Router and forward
traffic from the eeePC. Have to reconfigure both devices when you switch
between the two modes of opperation. Not sure how you'd automate this
without creating a security issue.

I shall for the time being minimise my messing ;-)
