Pierre, I don't think there's any question that the data limit is a function of the UT, not the satellite. What I don't know is the size/cost/complexity of a terminal capable of B/B data rates. It will be bigger than the G* handset, that seems certain; but maybe it can fit the "budgets" (mass, volume, $, etc) of a passenger automobile, and compete with other data services...we'll see.

Pierre, I share with you the hope that G* will finally start seeing itself as a data service provider to automobiles in the US (and planes and trains elsewhere) However, unless a downlink geo birds are used as a feeder links as in todayïs InFlight news, i donït think weïll meet peoples expectations. Also sat/cell handoff is one of those things that, with the existing technology would cost a great deal of time and heartache for not too great a return. Youïre getting better trunking efficiency (that is you need less system resources to handle peak loads) but on the other hand there would be substantial signaling, synchronization, battery and time delay issues. Not intractable, but perhaps when 3G comes along with a distributed IP "switch" cell/sat handoff would be more practical.
