Well, this is a surprise.
The licensing terms are predictably restrictive and the licensing process is anachronistic at best (I was going to write “medieval”, but there are no carrier pigeons involved).
I fully intend to give this a whirl and see if I can tie it in to some of my personal stuff (I have Mathematica installed on my lab Raspberry Pi and fiddle with it, but being unable to tie it to APIs and re-use it somehow has severely curtailed my explorations).
