Just something I'd like to play with, I would like to create a "virtual" file/directory in the File System of Linux or Mac OS X (Not sure if I can share the same code - does POSIX help?), for example /foo and then perform custom code when something is read or written to it.

Similar how /dev/null allows for stuff like

echo "Hello!" > /dev/null

I don't care if it's in /dev, /proc or anywhere else, as said it's mainly something to play with...
