I think it's a bit more tricky.  /dev is a wonderful example.
By default it contains only device entries:

	/dev/tty
	/dev/st0
	...

which you could nicely support by a dev fhandler.  The problem
is that I wouldn't like to disallow to create symlinks inside of
/dev:

	ln -s /dev/st0 /dev/tape

So /dev is kinda `bastard' containing virtual device entries
but also real symlinks.

In that case it would make sense to support reading the real
/dev in the Cygwin tree on disk plus listing all virtual
device entries.  Sure, you could manage that in the dev fhandler...

I think that you'll have some work to implement that due to a
design constraint inside of Cygwin.  In theory the functionality
of stat/readdir etc. has to be moved inside of the fhandlers
first.  While that already works for stat on disk files it's
currently not implemented for readdir at all.
