  Agreed. Even better: pick a strategy on resume from sleep!

  This would be a good thing, I agree, but I have a better suggestion:
  1. get your friend to install dhcp on his network, giving you a fixed IP
	address. Use dhcp all the time.

  2. we need to modify our /etc/dhclient-script to allow configuration of
  more things. If the dhcp server doesn't provide them, then they need to
  be taken from some file indexed by default gateway and/or IP address
  assigned. These would include:
	- SMTP smart host if applicable
	- HTTP/FTP proxy  if applicable
	- NIS domain
	- DNS search order

  Probably, the default gateway should just pick a configuration from
