I don't see why you could call it anything but a software router.  That's 
sort of why things like it and the 7500 before it lasted so long.  As the 
thing ages, cisco comes out with new NPE (or RSP/VIP) processors with 
faster CPUs / more memory capacity that are able to move more packets. 
i.e. NPE-100->NPE-150->NPE-200->NPE-225->NPE-300->NPE-400->NPE-G1->NPE-G2

You could start with a VXR with NPE-225 and keep upgrading the CPU and 
keep the thing in service with the same interface cards 15 years or more.
