On Unix (though not on cygwin) I've previously solved such issues by 
writing a script that collects symlinks to the contents of some list of 
directories in a few (system and/or user specific) directories. These 
few directories then take the place of the list.

The script will need to be re-run whenever there are changes to the 
directories on the list, but that can usually be automated.

Cheers,
Wolf
