Absolutely so! In order to provide natural migration and progression, we
should use the last mile approach. Rather than establish the whole thing at
once (never happens) we should keep on pushing IP further and further down
the last mile (or 600 in our case). 
As you said Keith, IP on the ground is common place. IP to space vehicle
isn't and has been done only to a limited extent. On board routing is the
next frontier. But by using the last mile approach, we should try to move IP
from the ground station boundary to the space vehicle boundary. Even if we
don't have on board routing, we gain the advantage of having an IP system
that will be compatible with future - fully routable space platforms.
Also, most modern platforms come with upgradeable IP stacks and protocols
(most RTOSes that is), which is in sharp contrast to the softwired customs
protocols.

If we accept that we want and need a routed infrastructure in space in
the future, why wouldn't we want to start putting it in place with
missions currently being built. If we start launching some of our future
systems with no routed IP, is there a clean path for them to "migrate" 
and be full participants in the future network. More importantly, since
the lunar systems are new systems, does it make sense to build some
using legacy protocols, then have to upgrade them to support future
IP protocols, and also do long-term support of gateways to support
interaction between legacy and IP systems. Isn't it more beneficial
to take this opportunity to deploy a whole fleet of new systems and
start the first systems with the technologies we want to end up with.
