Cooperative path computation are highly theoretical at
the present stage. I think there might be many
assumptions and approximations to prove such strategies.

take one simple example: Throup et all describe 
methods for optimizing OSPF weights by using heuristic methods
..esp local search hueristics (tabu...) But in reality, people
generally use standard heuristics (like Weight inversely propotional
to capacity.) So i think as a least option we may choose some standard 
heuristic assumptions for solving such co-operative path computations.
So using tabu search methods are sometimes not practical.

Solutions might be novel. We introduced IPv6 long before but still
we could not transfer to new structure all together. we go for 
increment methods like CIDR, NAT, double stack, and ALG than transition
to a new addressing structure. So, it is always advisable to do some
incremental techniques than novel solutions. But, if you are proposing 
new structure, first we should address flag day  problem will 
trasitioning. i dont think any new systems does this work.
