Neat...and on a somewhat similar note (bash enable -f hacks), some bash FUSE bindings I wrote a few years back: https://github.com/zevweiss/booze

I initially wrote it basically just for giggles, but was rather pleased a few months ago when I realized I could use it for something I actually needed, and it was just the right thing (presenting a mount point that acted as a view of the differences between two rsnapshot-style hard-link trees -- only took a few dozen lines of very simple code).
