The only thing I can think of is a daemon that uses the extended-ioctl
callback function that's in Linux. E.g., notify when the file is read,
written, removed. Not a standard unixland facility, but who cares? I'd
be writing this for a Linux device driver!
Seriously, though: assuming udevfs is the deus ex machina for 2.6-land,
which dists are planning to use it?
