I'm one of those who wishes for control.  The G1G1 offering has set 
up a user population different from the education design of the OLPC 
project.  I live in the boonies, have no wireless, and there are no 
other radios within range.  My connection is by wired ethernet.

Took me a while to find out that NetworkManager would set up my 
wired connection, if I provided a DHCP server.  However, if I happen 
to unplug my ethernet cable for a while, NetworkManager reverts eth0 
back to radio (and I need to reboot to reconnect as wired).

What I wish for is a user toggle that when I'm at home will inhibit 
NetworkManager from supplanting the wired connection.  (But I do 
want to restore radio function when I take my XO to a cafe.)
