Just had a thought. There's a compact USB to BT adapter that most of us already have: our current NITs.

If this issue is the only thing keeping you from leaving the laptop at the office, then I suggest throwing your n8x0 and your OTG adapter in your briefcase for just such situations.

Make sure your Maemo devices are already paired and copy the data over BT.

Someone needs to write a Diablo app for this purpose!
