I'm working on something similar (Score 1)

I'm working on something similar: I've hacked into the tcsh source so it will, before saying "command not found", send your command over a TCP connection. On the other end I've got a PennMush server. So far I just use it to chat at my terminal with my friends, but ultimately I'd like to add cute interactions with the filesystem.

I call it mutcsh.

So far it's in no shape to share, but if anyone is very interested, let me know.
