Running a script as a config option, sure.  Supporting multiple simultaneous 
_upstream_ networking interfaces internally?  Seems overcomplicated for the 
common use case, and the script is an easy way to punt.

Even the common case of a router wouldn't need this, because you only run the 
dhcp _client_ on one interface.

Now admittedly my laptop does, because I sometimes use eth0 and I sometimes 
use eth1, and I suspend rather than shutting down between them.  But a script 
could handle that easily.  (I could also be using multipath, or some trange 
tunneled vpn, which would be silly to try to do internally but which a script 
could also handle.)
