You could indeed set up a TCP client/server model. The server
could be stand alone, or be run from inetd. You could use a
model where you make a connection for reach request, or you
could have a permanent connection. You could use UDP for
communication as well. Or you could create a file or database
with all the quota information, which you update from the
NFS server once every hour/day/week/whatever, and consult from
the webserver side. Yet another possibility is to forget
the entire web thing, and have people just type 'quota' on
the box itself - after all, if they don't have access to the
box, it doesn't matter what their quota is.
That's a decision you have to make, and what is the right
decision depends on many things. But one thing that hardly
plays a role in which solution you are going to take is
the language in which the solution will be written.
