Skype co-founder Janus Friis is backing a new communications app called Wire, out now for iOS, Android and Mac OS X. The app itself is the reimagining of how a communications tool like Skype should operate had it been built today. Much of that, in Wire’s case, means under-the-hood improvements that users don’t necessarily see, such as advancements in media processing, audio technology, file compression and delivery, and more.
