There is both WLAN and USB support in Mobile hotspot nowadays. Is there a plan to get also Bluetooth-PAN-support integrated?
Do not know how it would work with Windows, but for example with Linux, I would want to just run Mobile hotspot on N900, choose Bluetooth as a "Connection" method and then Start. On Linux PC pand-daemon (--listen) would notice connection established and do the deeds on that end.
It would be just so convenient consistent to have also that in Mobile hotspot and not needing to run manually separate scripts for PAN-connection in N900.
Having Bluetooth tethering is I think most suitable for me. 1) Compared to WLAN because no need to use so much power as for WLAN and broadcast packets widely. 2) Compared to USB, I can charge the battery quicker if USB is not connected to PC and were there also this feature (?) when USB is connected the CPU never sleeps.
