I would only point out that Cygwin does things this way to maintain
compatability with FAT32 which doesn't support magic file types on the disk. 
So the only way to do it is as normal files with special contents or
attributes.  I do believe however that Cygwin compiled apps (samba etc) will
respect Cygwin's magic files.
