For quite a while now, I've fantasized about creating an object-oriented toy OS with an OO shell and something akin to Classic Mac OS's resource forks. As much information as possible would be stored as OO data structures in alternate file streams with native tooling to query them.

It would need to be based on Illumos and not Linux, though... IIRC, the only existing open-source filesystem that supports anything akin to a resource fork is ZFS, and the Linux kernel doesn't have the syscalls readily access it (ZFS implements extended attributes as forks, but the kernel has really tight limitations on what can be done with xattrs, much tighter than what ZFS can do).

It's just a fantasy, though, and not something I have the skills or the time to do.
