I thought about doing *s but in the world of Classless Inter-Domain
Routing where not all networks are /24, /16, or /8 it seemed a bit
imprecise.  But, maybe that doesn't matter.

I think the more important difference with your proposal here is that
it is passed as a new attribute called 'gateway_ip_template'.  I don't
think that attribute would ever be sent back to the user.  Is it ok to
have write-only attributes?  Is everyone comfortable with that?
