 This can be easily done. I'll just make net.lo* not provide net.

As soon as you add a second interface, this default "net" service
breaks. That is why I think we should add an "internet" service that
consists of interfaces the user says provide a connection to the
internet. Then we could make our services that need real
internet connections need that service instead of net.

This one or all functionality you are talking about is already available
through rc_depend_strict.

Also, you can set up virtual services already (see the rc.conf section
on dependencies).
