TFS sounds a lot like Korn and Krell's 3-D File System.  Given AT&T/SUN
collaboration, it is possible that they are the similar. 

The 3-D FS adds a notion of "views" -- higher planes of file trees which
can be laid atop the base tree by the user.  Special privileges are not
required.   To get at the lower layers, you prefix the hidden component(s)
with ".../".  See the 1989 Summer USENIX proceedings for details.

(And you thought symbolic links caused security holes?  Just wait! :-)
