I don't know what arbitrary PPP and VPN clients can and can't do.

The stock dhclient supports multiple interfaces. Obviously it
doesn't know how to handle multiple global configurations by
itself. Like resolver addresses or, more important, default routes
or any other option the DCHP server could send you.

But you can give it some decision-making policy for that in form of
a shell script. And you can handle arbitrary data this way.

Saying that... some software that handles resolver configuration
for multiple 'configuration clients' is surely a nice thing,
but it isn't even half a solution.
