In particular, here are some sample usages I could see as handy:
USB spectrum analyzer*: Could be used for temporary troubleshoots or permanent addition, also more cost effective than a full AP analyzer unit since you could re-use/move the USB analyzer around to different AP 70s where/when needed.
USB GPS receiver: Allows for more detailed location tracking and RF calibration since you could now tie an AP location to a earth-bound coordinate rather than just going off of 802.11 related statistics, e.g. An AP at x,y,z lat/long/alt sees other APs at x,y,z and SNR/RSSI is X between them, which can also aid in client location tracking.
Adding additional radios to the current AP units to support future 802.11 developments, or adding backward compatibility radios to solely support legacy clients while using the internal radios for higher speed clients (the Atheros AR5212 radio card used in both of the AP 70 radio slots is an A/B/G card according to the AP boot messages).
Note, the two USB usages marked with * are briefly mentioned in the AP 70 Installation Guide, but I haven't seen any specific plans called out for how these applications will be fullfilled.
Thanks for any and all information!

Right now there isn't any formal support for the other items you've mentioned. We've done some work prototyping different uses of the USB port in our CTO labs and through some of the Aruba Labs projects. We're investigating some of the items such as spectrum.
I'd be interested in hearing more about how you would use the GPS connection. You're right, you might get a more accurate picture, assuming you can get a signal, but would you put one in every AP? Seems expensive to me but I'm always open to hearing about use cases.
I'm not sure what the RFID case is for USB, but you don't need to hang anything off the USB port of the AP to make this work. Take a look at the following page around our partnerships in this area:

Another group also installed 'mote' sensor devices, which provide temperature, humidity, light level, sound level, and vibration. A motion sensor could also be a useful widget.

Will we be ever able to use the USB port as storage for boot parameters, for example? Just like some industrial grade switches from Hirschmann that use such a port for easy provisioning on RMA replacements. An inexpensive USB stick could let L1 support replace dead AP without wasting expensive L2 resources for re-provisioning.
