Dedicate a small segment of bandwidth and send updates
continuously. Clever software will recognize what it 
needs from the stream. Never allow the update to go
live unless it checks CRC and equals a second d/l, then
provide the rollback button for clearing a glitch caused
by local hardware. None of this is rocket science. <g>

OTA, the upgrade hardware is paid for as part of the
set purchase. The only issue in the early years is that
the base must continually expand to keep Ibiquity's 
revenue up. After about 10 years the first generation
will lie in the scrap yards and the process repeats.
Not long after that digital increases power and analog
goes away. Then, we have a real system. But I fear the
scenario won't be that rosy because Ibiquity will do
their best to kill the goose with greed.
