Here's an interesting blog entry by Charles Stross, author of freely availble SciFi ebook Accelerando (Thanks Mr. Stross!) and his take on DRM, it's the one from March 27, 2007. He has some quite interesting anecdotes about what defined a "pirate" of books prior to the eBook generation, but the article is interesting nonetheless. I particularily like his take on why the eBook market is broken, DRM, piracy, etc., where he pretty much hashes out what we've discussed here over and over, though he backs it up with a little more insight. Quick read if you have time.
If this has already been posted, just zap it. I've read so many articles on here they all seem to run together... though I did perform a search prior to posting.
Edit: Sorry, forgot link!
