I agree that having to mount another filesystem to get at network
directories is an awful way to do things.  First it requires root privilege
to do it, and it also fills up kernel mount tables with lots of NFS
mounts.

I have to disagree with the // concept though.  It adds special meaning to
something that in BSD just means /.  I know of several programs that
were written for BSD that just tack the / out front of a directory and would
break with this new interpretation of //.  (Please, I didn't write them so
don't blame me for this one)

Mach introduces a better concept, I think.  It uses a more robust symbolic
link mechanism that allows you create a symbolic link to something on the
network.  (I think it is Mach, but I can't find it in the manual, maybe it
is in the Andrew Filesystem)  This seems to be a better solution.  Every
user can create one, they are stored in the filesystem not the kernel, you
can mount a file or a directory (try that with //), and the concept can be
expanded to specify the network filesystem type that you want.
