Open Source License Question

Following a link in the article that I was pointing to, I found yet another 
interesting article.  See especially the "Choosing a License" section in 
http://www.oreilly.com/catalog/opensources/book/perens.html.  I didn't know 
about the X license before, but it sounds intriguing.  Michael, you may be 
interested in that or in LGPL.
