Expect all ATM to move to IPv6 and WIMAX in the near future. The actual network and transport layers are transparent to the applications like FANS. I also expect that FANS both 1/A and 2/B will be totally replaced by a more capable system.
See System Wide Information Management (SWIM), Flight Information eXchange Method (FIXM) and Weather Information eXchange Method (WXXM) and Aeronautical Information eXchange Method (AIXM). All will be available over Aircraft Access to SWIM (AAtS). SESAR and FAA have to settle a few standards issues. But ATM will be enhanced considerably.
I don't want to hijack the thread onto a totally different area that should perhaps be in Tech Log.
