ssh user at host df | awk '{print $3,$4}' > host.df

Should get you started.  cat all your *.df files together, work a little 
awk magic(1) to get the totals, then convert to K/M/G or whatever you 
prefer.

This would assume that you have a private key set up for each box you 
are sshing into, so that no interaction is required from the script and 
that you don't have duplicate mount points on the same system, ie a 
slice isn't mounted in more than one place.
