It's possible that this represents insight worth sharing
broadly, so I'm copying the list.
It isn't immediately obvious to me why file descriptors would
have had a major impact, so can you elaborate?
Down at the end of this page
there is a list of pseudo-filesystems including portalfs from
FreeBSD, which allows nework services to be accessed as a
filesystem. For those interested in pursuing the idea, you should
have a look at FUSE <http://fuse.sourceforge.net/> which allows
anyone to create resources in the filesystem namespace, for instance
by writing a Python script
FUSE is also availabel on OS/X <http://code.google.com/p/macfuse/>
It should be possible to register a URN namespace to go along with this
API so that you could have
to represent a service that is provided by the courselistFS on some host
that example.com knows about.
