It could essentially make any plain text filesystem available as regular web-friendly html files, convert troff source to postscript, convert plan 9 images to png, and much more. You can even present device files as json for modern web applications.

May be create a generic filter-fs that can be controlled with a script that can be updated via a control interface? Almost a mkfile like script so if a rule exists for .md -> .html, any listing will show foo.html instead of foo.md. Reading foo.html will transparently invoke a conversion program. You can get pretty clever and may be even install a src dir under /bin this way to build binaries on the fly! Or even just the presence of a mkfile in a filtered directory would be enough for this behavior. Taking this further, an installation of a new machine can be made instantaneous! Just use a local cache for all the binaries as they get built! Obviously this should be called mkfs :-)
