This is one thing I hope they get right: it's the right thing to do to focus on a first implementation, but in the end what is more important is the protocol that emerges from that. If the underlying protocol is solid then you will get independent people writing ports of it to every language under the sun in no time. On the other hand if the underlying protocols are either flimsy or technology dependent (specific to ruby or some other part of their stack) then it's going to really limit how much this can spread and how much involvement they get.
