"TechCrunch is saying that Skype is looking to buy Gizmo5, a SIP-based service that isn't quite as popular as the former, but works pretty well. SIP is an open standard that works with many, many devices—Gizmo 5 works with Google Voice even—so this could be a pretty good move even if Skype gets out of legal trouble. Imagine piping your free Google Voice number through Skype to get free calls like you can now with Gizmo5." - Steven Perez from Bookmarklet
