I sympathize with how overworked OLPC developers are.  But a number 
of G1G1 systems are getting into the hands of articulate net-aware 
people.  If they become disenchanted by the Legacy IP performance of 
the OLPC, what they say might result in hurting the whole project.

I don't have wireless at home.  First tried stopping NetManager, and 
manually setting the IP address.  That worked, but screwed something 
up so I could not use the system in a cafe.  So I restored the OLPC, 
and added a DHCP server in my home, __just__ for the OLPC.  Effort 
that I had not anticipated needing to expend.
