Actually, if you think about it, it's not all that hi-tech at all
considering what the Apollo file system does already. The extensible
streams functions allow the user to evaluate any sort of function that
he/she cares to write code for. It just takes the time for someone to
sit down a do it. One simply (simple if you're used to write new
object type managers) has to define a new type of link which tests
if the object pointed to is available, and if not, tries an alternate
object.

While I'm at it, does anyone know if Apollo teaches any courses on
writing type managers using the Open System Toolkit. I glanced through
the manual and it was less than crystal clear (at least for people who
aren't used to writing file systems).
