OK, I'm convinced.
I added a new option, "no-dhcp-interface", which is like
"except-interface" but only disables DHCP. That's the best
backward-compatible scheme I could create.
so now you can do
interface=eth0,tun0
no-dhcp-interface=tun0
and have DNS on both, but DHCP only on eth0.

now.
Cheers,
Simon.
