   Is this the proposed stacked route system?

Yes, for output mostly.

Also the idea Alexey and I have to move towards a small
efficient flow cache shared by IPv4/IPv6 plays into this
as well.  There are changesets on their way to Linus tonight
which moves ipv4 over to using ipv6's "struct flowi" from
include/net/flow.h as the routing lookup key.

The initial ipsec is intended to be simple, singly linked
lists for the spd/sad databases etc.  Making the feature
freeze is pretty important right now, full blown flow cache
is just performance improvement :)
