Yup.  As others have mentioned, OOB is one big use.  I'm not
daring enough to use a RaQ as a router, or else one could attempt
that.

Note that you'd need to run bridging if you wanted IP addresses
from the same subnets on different ethernet interfaces.

By default, I agree.  However, one _could_ block outside traffic
to the GUI website's ports... that's one pseudobenefit to port
perversion:  It's easier to configure than proper anti-spoofing
and IP-based website restrictions.

I agree.  Some might contend they weren't designed to serve WANs,
either. ;-)
