Create a cron job on the server that builds a file with the available
disk space, output to a file under one of the read-only modules.  Then
your client(s) may read that file via rsync.  Even better, allow a tcpmux
service to just output the usage in real-tme.  This helps avoid races where
all the clients think there is lots of avaliable space.

I use RFC1078 services for anonymous, read-only, real-time data services
because they are super cheap, and sys admin can code them as shell scripts
or perl programs.  If you need code examples, reply to me.
