Hello all,
Does anyone already has a program something like pipefs (or cmdfs) ?
That is a service program by host owner to his users.
The command syntax will be
pipefs [-s name] command
which creates /srv/name (default /srv/pipefs)
Users can mount and execute the command
mount /srv/pipefs /n/pipefs
echo 'blah blah' >/n/pipefs/data
giving 'blah blah' to the command.

execnet(4) seems close to what you want, but not quite right - it
provides arbitrary command access, rather than a single command (which
could make sharing it awkward).
i think closer to what you want is' geoff's cmdfs (in his contrib
dir). it's only advertised to run on third edition, but if it doesn't
run on current it could be a good starting point. the comment at the
head matches what you want pretty well:
/*
* cmdfs mntpt cmd - mount this file server, writes into which become
* writes to a pipe to cmd. a new cmd is started for each open
* of mntpt/pipe, but only one is permitted at a time.
*/

mfs (in contrib, nemo, planb, sys, src, cmd) is similar to this, and
works for 4th ed.
