Technology-wise there no problem with Wifi and Bluetooth at the same
time. They both use the 2.4GHz band but with a quite different usage
scheme. Wifi uses a single channel constantly while Bluetooth hops
within 16 channels at a rate of up to 1200 (?) channel hops per second.
So even if Bluetooth happens to hit the same channel it will just be for
an amount of time that Wifi would simply ignore - like a small
transmission error ;)

Concerning headset usage I just had a chat with Marcel Holtmann (the
BlueZ maintainer).
He sais that it would be possible if Nokia and TI would release the
specs for the chipset and the connection of the chipset to the rest of
the system concerning audio.

That would be cool!
