In all of the cellular systems I've used so far, roaming is only half
automatic.  In particular, to place a call to a roamer, you have to dial
the roamer access number for the area where they are, and then dial their
phone number.  This amounts to source routing, which is even more of a
pain for mobile destinations than it is for "static" ones.  Bleah.

Maybe Motorola's proposed satellite-based cellular system will be better.

That's it!  We put the core gateways into geosynchronous orbit... :-)
