@kallisti I mean, it *is* Dis. The kernel exposes the VM to the userspace.

There is node9, which is intended to interoperate. Basically it's Inferno, with the Dis VM removed and Lua added. The idea was to be able to talk between them, sort of use the Inferno bits as a substrate for a heterogeneous network. The project is a spare-time deal for fun and last I tried it, it's still really rough, but you can get a Lua prompt and you can (sort of) interact with OS-level facilities.

If you mean something like whether Limbo has been ported outside, I think the closest to that is Go. Limbo and Go are about 95% similar. Modules are different, Limbo has linked lists and tuples, Go has maps.
