Received a Ben NanoNote today. It is a really natty little device with a lot of potential.
My standard test on how hackable a device is involves getting Guile running. Anyway, it was pretty easy to accomplish this despite not using openWrt before.
guile> (map (lambda (x) (+ x 1)) '(1 2 3 4 5))
(2 3 4 5 6)
To install get the 3 xburst packages from here.
