Thanks for the heads up Tanner. I vetted the script before I put it on my server. It does exactly what I wanted it to do. Also, it also came with Wietse Venema's stamp of approval - which is (in my opinion) a pretty damn good endorsement.
There were a couple of others that I also considered, but since I wanted to get it up and tested this weekend I didn't have time to vet those. <jon quick checks the latest load stats again...> Yep, the load stats this morning are much lower than normal :-) The greylisting must be slowing down those evil bots! There is a greylist app written in C (described on one of the excellent sites you point to below) that I'm going to look at later on, but for now this simple perl script is a champion. 11 hours + after greylisting was initiated and no spam has made it through. Very impressive.
