Separating out loopback setup is probably good since loopback always needs
to be there no matter what other network interfaces are enabled...

This all sounds nice in theory--but will it be extensible, or will all
enhancements of this method have to be implemented in Corel's network-setup
(or whatever) package?

If you're doing enhancements, maybe it'd be nice to have a more robust (in
terms of hardware changes or kernel recompiles) way to specify this.  For
Ethernet, maybe MAC address or driver would be good.  OTOH, 'eth0' is good
for single-interface (or single-ethernet) machines since it makes it easy
to change cards.

Filfre to say 'show me the code' if you think this would be too much work
to implement...

There are several kinds of dynamic ip address assignment--rarp, bootp,
dhcp, as well as separate methods used for slip and ppp.  Hopefully this
method won't be limited to just dhcp.

Perhaps separate packages could choose to implement arbitrary network types
... it could become a useful hook like the menu system.

good idea

maybe also have a 'name =' field so that people can use friendly names
(like 'inside', 'outside', 'dmz', 'sales', 'production', etc) if/when
routing and forwarding configuration tools are built that work on top of
this scheme?
