Interesting concept.

Problem is from the above page the download site doesn't exist.  With a 
swift whack of a clue stick I searched on rpmfind and got it.

For S&G I ran it against a host I admin and got some interesting results 
that didn't have anything to do with the time.  I got several messages 
like this

	bing: packet (92 bytes) from unexpected host 66.190.251.135

which interestingly enough reverses back to

	ts46-04-qdr901.mdfrd.or.charter.com.

There were many other IPs.

I have a bit more reading to do but can any network experts on the list 
explain what this is?
