It would be pretty much ok for read-only access to static data - I have
used such setup for my old (unavoidably path-bound) software collection.
But of course you are right, it should *not* be used.

You see, I have never encouraged it! :-)

No, please, Jan, devote your time to real development instead of
fixing such workarounds! As said, there *are* cleaner workarounds
available when really necessary.

In my point of view it is a good means for transitional workarounds,
but of course in the long run it should be empty, delegating the cell
resolution to *the* suitable distributed service, dns.

Thanks for taking it up. Most of users and system administrators as well
are still not accustomed to crossing administration boundaries. It is
*then* one notices the evil side effects of the filetree view
administration on per-client basis (like the shortcuts or say mounting
Coda at a different place than /coda) ...
