New address families (like ipx or IPv6 instead of IP) need a new .defn file;
new methods for bringing up an interface in an old address family (ISDN
connections, say) just need modifications to an existing .defn file. But
yeah, that's the idea.

I suspect the main thing that could do with enhancing is the .defn
file grammar. Working out a convenient way of properly dealing with ppp
and ISDN might be better with a different structure, and it'd be nice
if options weren't simply text substitutions, so that
could be correctly translated to IP, netmask and network automagically.

I'm not really sure what you mean by bringing a little more structure into
it. I'm somewhat inclined against structure that's not immediately needed
and useful, on the instinct that it might prove annoying when we later
find out that additional structure *is* necessary, but that it's not the
structure we tried first. I can probably be persuaded otherwise though.
