This may be overkill... info you probably don't need to spend time reading, but it was interesting to me.
I was looking up the lyrics for "Meadowlark" as sung by Sarah Brightman, and came on this website that covered law and the internet... and more specifically copyright
At the bottom of the cited page, is a FAQ list that delves into how law covers internet activities as pertains to copyright. The "About" link at the top of the page cover a wider range of the legalities involved in use of the internet.
I was particularly interested in some of the points of law that cover what is "acceptable use"... fewer restrictions than I would have thought. Leads to wondering if many of the Tech IPO's will be able to protect against copycats. Many of the current court challenges have not been adjudicated. Literally billions of dollars at risk, depending on these decisions.
All in all, an eye opener for this non lawyer.
