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 :-) ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T745cda5087701a0d-Me5af03b18c19111f8ced87fb Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
