When I gone through the draft, I co-related things with
ls and cat.
it is better to compare the protocol to the Unix system calls:
readdir(2) and open(2)/unlink(2). you can't specify a
pattern to either of these, that work is left to the client
application (actually sh(1), not ls(1) or rm(1)).
Excellent comment ! I agree.
My only concern was that client and server systems could be
different, ie., In between network comes into picture. The
no. of transactions between server and client also matters.
