With a high quality audio codec and a softphone all of a sudden voice at no cost (i.e. Skype, Yahoo Messenger) becomes a very interesting proposition.
Imagine the idea of this Junxion Box with Skype or Yahoo Messenger as the way to talk back to the mother ship. With unlimited data for 80 dollars a month or so this means that cellular traffic craters within select environments. For example, the Nextel Direct Connect service is a high margin, very profitable offering. This rips right into that market via audio IM, which is all Skype really is, but full duplex.
More importantly it means if their is EVDO access, Junxion Box makes it shared, just like a Wireless Router does in the house.
