Imagine extending Plan 9 semantics with something like REST style protocols, but via the (virtual) filesystem layer rather than HTTP requests. (Offhand, I've never touched Plan 9 but...) Hypothetically /proc/SOMEPID/db/DATABASE/SCHEMA/TABLE/various views which provide expressions in some order. Or /proc/SOMEPID/containerofthings/ and the directory listing is serviced by the application, as an enumeration of keys (filenames) to values (datasets). For a database the API would behave similarly to how ORMs operate since filesystems are inherently similar to objects.
