32k of flash for the Arduino. A lot more than my old 4k TRS-80 Model 1.

It's a microcontroller, with significantly less functionality than
my wristwatch. The big configurations have something like 8k
of RAM and a few hundred k or flash. The regular ones have
a couple of k of RAM and a few tens of k of flash.
There's no OS, just a single running application.
I'm pretty sure it'd be possible to implement a cut down version
of the PG protocol for it (though for the use case the original
poster mentioned it's a terribly idea, for system security reasons
as much as anything else). It'd be an interesting Saturday
afternoon project, at least.
But running virtual machines on it, or doing naive ports of
a full featured API isn't going to work - there's just not
enough space on the chip, for either code or storage.
Cheers,
Steve
