Cloud-based "Video Game Advertising Network" Gaikai quietly entered a more open phase of beta testing over the weekend, and will be accepting 10,000 new testers. Here's word from DPerry.com: "The game everyone is playing first is Mass Effect 2, it's the highest rated PC game in the last 12 months and Bioware simply rocks. They've been very supportive as has Electronic Arts. The good news for them is we are getting a surprising amount of people clicking "BUY" without even making them a special offer."
