I'd like to see Bluetooth available for RISC OS. I would prefer it to be via a dongle (most of the dongles out there seem to be just the one Broadcom design, which should simplify things). If A6 are doing it on the A9, I think they ought to do it via a dongle there too.
Give the A9 USB2 - that would be an improvement. Give it BT support via a dongle. Sell BT via a dongle to users of UNIpods and Simtec USB podules. They should be able to make some money on that
