A handful of you have asked if usb otg is going to work on the N9.

Well as you can see here
someone has asked for an n950 to work on developing usb otg for it.

66: USB hostmode. Give N9(50) access to external storage etc. (co-devels: Thomas B. Ruecker, MohammadAG)
Review the core functionality and find other similar fields to tackle (see *# starhash-enabler for N900). To mind comes: user profiles (refer the modest "default" & "silent" on fremantle), dialplans, location aware event triggers (cinema profile triggers automatically on entering the building), improved battery management and monitoring, theft protection and recovery...

cablefinder based on fast magnetometer readout detecting 50/60Hz fields (co-devel: alterego)

torch/flashlight app for N950 - possibly augmented to do optical data transfer, RX via a v4l2 based decoder app
