DPerry.com announces that Gaikai is live, offering a cloud-based service that is now called a "Video Game Advertising Network" (thanks Big Download). There's a lengthy discussion of the measures they've taken to reduce latency on the service, and this outline of the games currently being offered:

You can try Mass Effect 2 if you just visit: http://www.gaikai.com/ (Just wait and if your connection quality to our Server is fast enough, one of several pop-up designs will appear.)
You can play Dead Space 2 here (after a short survey): https://www.surveymonkey.com/s/F2QFNY7
You can play Spore here: CLICK HERE
You can already play SIMS with Gaikai here: http://www.thesims3.com/trial
You can already try Second Life here: http://maps.secondlife.com/ (Just wait and if your connection quality to our Server is fast enough, a pop-up will appear.)
Our next phase is to start embedding Gaikai into gaming websites, so visitors can try the latest games. We already have run millions of connection tests, but the more the better.
