What we learned with Mobitex and later Datatech was that there were some really interesting applications that were being developed, and we were right there while it was happening. But it took a lot of faith. You call it vision, but it's a combination of vision and faith that 1) it's going to happen someday, and 2) it has value, and 3) you can actually accomplish it in an economic way and promote it so that you can fund the development and growth of the business. That's pretty tricky stuff.
