ApplePy experimented with providing a client-server model years ago for the 6502: https://github.com/jtauber/applepy
It's great to see somebody picking up the idea again and extending it.
It's a cool idea. Lots of possibilities for fun RPC projects with distributed processing.
Remotely accessible 80-column cards and custom mappers FTW, eh?
Good reminder that projects are meant to be implemented.
