"aimed at ultra low-power devices with as little as 64 or 32MB of RAM."
I know Moore's Law and everything, but damn I must be getting old because that's not low-power by my standards.
My low-power standards are an MSP403 microcontroller running on a coin-cell battery.
Granted, it's going to be hard doing some level of interesting IP networking on that kind of hardware, especially with the increasing requirement of cryptography.
Maybe something slightly beefier running Contiki [1], but I can't resist the reactionary thought that anything Android- (or even Linux-)related is way too fat for many IoT applications.
