[PD] More Sensor Questions inc libfreenect on the Rpi

[Julian Brooks]

Hey Martin,

Wow, like that a lot.  Needs some more digging into but looks very
promising.

Have you tried one yet?

Will get one and report back if not.

Next weeks too crazy but will get into it the week after.

Top tip, cheers.

Julian
