I think that is a very valid scenario, as is Karen's.

Our own site deployment has been achieved by using VLANs (I'll update my
draft on this) and we found that we can tag many different VLANs on routed
packets for a single interface on a BSD router.   We then split the real 
interfaces (and routers) as and when v6 traffic grows.   This leaves us
with congruent IPv4/IPv6 subnets/links and IPv6 on the wire everywhere.

This is the common method used by universities in the 6NET project, and I
suspect elsewhere, until capable L2/L3 equipment emerges from Cisco/etc.
