NPT66 doesn't solve that either, right?

I believe the DNS problem needs to be solved using split DNS at the domain
level, because in the general case that you have more than one VPN there's
no other way to do it.

This is a multihoming problem which needs to be solved anyway, and I think
it can be solved using source/destination routing.

If the VMs are bridged, it's no different from the multihoming problem. If
they are not, then how are they going to get addresses?
