We're using milter-greylist on a handful of small (hundreds of users)
mail servers as well as SpamAssassin, j-chkmail and Clam-AV and are
planning to enable to greylisting on the central mail service (tens
of thousands of users) next week.  We have been using greylisting on
the secondary MX for our central mail service for months and have
noticed a significant decrease in spam as a result (spam and viruses
often target non-primary MX holders).

I have ugly Perl scripts which parse information on greylisting
from the mail log and produce MRTG/RRD style graphs, the results of
which you can see at http://noc.uwaterloo.ca/~dkeenan/greylist.html
The scripts are specific to sendmail's log format.
