Yes... of course... In my above mentioned psion remote control, these files are not present on the actual filesystem, only when accessed by NFS, and the NFS-daemon does not treat them as files, but as commands.
I guess the /proc/ files could be used directly in the same manner?

Could you have a file /proc/empeg/play that will do a "play" function when *read*?
