I would refer these software engineers to IEEE-CS/ACM Joint Task Force on Software Engineering Ethics and Professional Practices.
Perhaps a more prominent website of names, links to prior art, claimed patent is a good idea?
Depending where the OSS patent fight goes, this may be a necessary tactic.
Update 29-JAN-2007 Via Simon Phipps look like this has been fixed. Yay. Also, looks like there is an EFF Patent Busting project. Haven't looked very closely at it, but looks like what I was blathering about. This + blogs is probably plenty.
Yet another example of why blogs are great IMHO. When every body has a printing press the walls start falling down. Yay.
