Well, one COULD make a utility called /usr/local/sbin/dirvish-imagesizes 
and put in something like...

echo > $FILE
for INSTANCE in * ; do
 echo "$INSTANCE - `zcat $INSTANCE/log.gz | grep \"Total bytes 
written:\" | cut  -d : -f2`"

smtp=smtp cat $FILE | mail -s "File sizes for image `pwd`" 
adminuser at example.com


Realizing of course that this only gives the size of the transfers..and 
not the base size.  I'd have to modify it to do a 'du' of the last 
image... and of course one would have to run this FROM the actual vault
