Actually, some network redirectors do implement these.  I think some
of the CD-ROM formats also have these in the root directory.

Of course, it's possile: just make ".." point to the root itself.
That's what Unix filesystems do, and that's what the DJGPP library's
emulation of "c:/.." does as well.  It works so well that I'm guessing
no one until now was aware of that.
