REST allows for clients and servers to evolve independently. If you can constrain that you can probably design something significantly simpler. That’s not a shortcoming of REST, though. The channel between your mobile client and your backend would probably be better served with something more like RPC than academic REST.

That's our proposal/challenge here, come up with a model that tries to merry the best of both world (RPC and REST) but still adheres to HTTP semantics and allow clients/servers to evolve independently.
