Visually it's not as striking as Kyle's fleet of dirigibles, but imagine a bank of devices working like mobile phones, connected to various wireless networks. Now imagine those devices also connected to the Internet. If I read the company's literature correctly, that's what you have with Xcelis. For a flat monthly fee, you can get unlimited wireless phone service. How? It seems you call Xcelis on your mobile phone, that call is treated like a mobile-to-mobile call (which increasingly is free) and then Xcelis uses VoIP to complete your call. Can't imagine the wireless providers will be too happy with that -- this could be an arbitrage business model that won't last -- but it sure is an example of someone building a better mouse trap.
