But if it requires understanding of a data protocol, it doesn't really matter if it's over the file system or a socket or flock of coked-up carrier pigeons. You still need to write custom user space code somewhere. Exposing it over the file system doesn't magically make composable applications, it just shuffles the code around a bit.
In other words, the transport protocol is just not the hard part of anything.
It's not hard, but it's sure a huge portion of the repeated boilerplate glue. Additionally, the data protocols are also fairly standardized in Plan 9; The typical format is tabular plain text with '%q'-verb quoting.
There's a reason that the 9front implementation of things usually ends up at about 10% the size of the upstream.
