The "if-up/down" and other scripts under PPP typically handle this.
You just need to set some routing "metrics" for the different paths to
different subnets.

At most, you might need to break out a little sed or Perl with a regex
or two.  There are probably examples already.

Yep.  Although this can be largely automated.  Welcome to _real_
(although basic) routing -- not the BS of a SOHO "NAT device."

<soapbox>God I hate it when they call those things "routers."  98% of
them have no such capability.  There are some major reasons for the
technical distinction.  Anyone who has had to yank rogue NAT devices off
of their corporate network should know what I'm talking about.
