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
