Well, once the hardware and drivers are ready I see no problem of using them in games too. But the whole article is too small and written in common words, so it's hard to go further. Speaking of RDMA - well, can you imagine a game that utilizes a 40 Gbps synchronous link? Maybe, communications between two data centers running one WoW realm (I don't know how scaleable their architecture is and if that's even possible) or something, but even for that (I didn't count, but at first glance) this looks kinda overkill. But anyway, once the low level supports something - I see no problem to rely on it in games as well.
