I think XC is a shared-nothing but globally consistent system. This lets you get some scaling up to a handful of nodes (maybe, charitably, a dozen...or two or three dozen), but as something that gives you ACID it is bound to have contention on the transaction coordinator at some point. I'd say it is closer to Oracle RAC in the space of use cases, without some of the nutty (but very impressive, and expensive) engineering to get this "shared-something" tradeoff RAC has.
