Is there an "internet" out there based on these sorts of communications? To me it makes sense to tie these things together into a global network independent of

  Not really for a couple reasons: 1. No encryption on any of the ham bands. They don't allow commercial traffic so to enforce that all transmissions must be decodable. 2. Bandwidth is scarce. 40 meters, which is one of the few bands open day and night is only 300kHz wide(7Mhz-7.3Mhz). For a frame of reference 802.11 has channels that are 22Mhz wide, almost 2 orders of magnitude larger. 3. The internet is really good at being the internet. When you move to RF you impose all sorts of constraints(see mobile/satellite vs fiber) so unless you have a really strong use case(one:many, mobile or no infra) wires are going to beat out airwaves every time. That said there's things like FaradayRF[1] that are working on building hardware/protocols that can solve the interesting use cases like delay tolerant networks and last mile delivery.
