I'm not 100% sure what you're asking. The package manager equivalent is in development but currently looks like a tiny wrapper around a hash->serialized_program database.
I think you need Python to be running the script on each machine.
You can also compile a scrap to C (and then probably from there to native, or apparently with pnut you can now compile to shell...)
Unison makes reference to a node I also could find scant details of rust.
