With the OnLive beta now underway (or at least starting to get underway) here in the US the folks at OnLive have announced that they will be
bringing the system to the United Kingdom at some point in the future. The company has partnered with British Telecom to bring the system to the UK with the possibility that they will be rolling out the system to Western Europe at some point after that.
I still haven't gotten past the "test your PC/connection" stage of the beta yet but I think there's some some serious potential in the service. Of course there are a ton of technical hurdles to get past and there's still a bit of uncertainty if OnLive can even deliver on everything they've promised. Still the deal is good news for those in Europe.
