As someone who has briefly worked with FUSE for my own toy projects, that seems like it would run into a lot of unexpected difficulties. Programs seem to behave very oddly if their assumptions about a file-system are incorrect.

But aren't the unexpected difficulties half the fun?

Yes. I expect many programs would have trouble, but you probably wouldn't have too much trouble making it work for typical non-interactive command line programs.

But the possibility game mechanics like making files appear after moving a file (an item in the game) into the directory (room) are really interesting.
