Actually, we had a POSIX port of Ling of alpha quality (e.g. no access to file system, a prototype of network connections based on libuv, etc) and experimented with running it on MIPS microcontrollers natively (not a great idea due to memory constraints and lack of drivers, but it could do simple computations).
