ECMP appears to be your main pain point, the rich features are not relevant, and you mentioned commodity hardware being able to hash on IPIP. I feel this may be a very special case where HW can do IPIP hash but not MPLSIP hash. Out of curiosity, what is this hardware? Jericho can do MPLSIP, I know JNPR's pipeline offering, Paradise, can. Or perhaps it's not even that the underlaying hardware you have, cannot do, it's that the NOS you are being offered is so focused on your use-case, it doesn't do anything else reasonably, then of course that use-case is best by default.
One of the biggest challenges we found of leveraging commodity hardware was locating a suitable OS that is not only fit-for-purpose in our service provider environment, but that could also leverage the hardware at its disposal to its fullest potential. It's hard enough for one vendor to get both their own hardware and software right most of the time. We posited it would be doubly hard for an operator to marry hardware and software vendors that do not necessarily co-ordinate with one another, if your goal is to run a profit-oriented operational network. Sure, the idea is great on paper, but there aren't that many shops that can throw warm bodies at this problem like some of the more established content and cloud folk. If it was easy, I certainly wouldn't have started this thread in the first place :-). Mark.
