Not suitable for full-table primetime I agree, but not totally
useless in other situations.  This is no much different from any
other 'move older gear from core to edge' scenario.  It all depends
on what you use them for.  Engine 2 cards are fine within the 
limitations (ie don't use ACLs, don't run more than 2Gbps etc)
which don't really matter for private AToM services etc, where
they work just fine.  I don't disagree at allwith the scenario you
posted though...

Yes - PRP-2 is sweet so far.

Of course, if you ever plan to go to XR on a given router, you need to
kill all the old hardware there (ie no 12008/12012, 12016 must be 
upgraded to 12416, no GRP/GRP-B, no Engine 0/1/2 LCs)  Time to join
the current century.
