I do not have much to comment except that that blog post is not one I
would spread too much... I might even tend to think it is a negative
blog post that highlights all the wrong aspects of Octave.... and btw,
I work with students from almost all ages and at least three countries
and they do learn the language faster when you let them into the
command line...

Anyways, I have used a Bluetooth to serial device
http://www.dwengo.org/products/bluetooth
in Linux is just another device...but indeed is B-to-S so is not
really a bluetooth device.
