Description: What I am trying to find is the analog to the pseudo-tty driver. The effect I am trying to achive is to be able to mount a filesystem across a network. It seems to me that the best way to do this is to have a pseudo-block device that has two ends. A regular end that is given to the mount command and a control end. The control end would receive low level commands such as read or write block. The process on the control end could then forward the requests over a net.

If this is not clear, please send me a note and I will try to elucidate.

[Historical note: I originally saw a version of this at the National Bureau of Standards where the remote filesystem resided on a PDP-10 (as one large file). It was faster to use the '10s disk than RK05s.(!) Unfortuately, this mechinism was tightly bound to the device driver for the link.]

Many Thanks, Lee
