Use VLANs.  It'll work if you give each exclusive IP instance a
separate VLAN on an interface (or a small group of interfaces).

No, that won't work.  We discussed it during the development of the IP
Instances (exclusive stack) feature, but the project team considered
it to be too complex at least for the initial version.  Exclusive is
just that: exclusive of all other zones on the system.

As long as you have distinct destinations for the traffic, that can be
made to work with shared stack instances, but you're right that it's
always been a bit problematic.  It wasn't the design center for the
original Kevlar/Zones project: all zones were expected to go on a
common set of subnets.
