Digital Interaction from the Print War Kids

I would love to read other peoples annotation in relation to mine. Were we both thinking the same thing? Are we both having the same thoughts or even what are you highlighting that makes reference to your life. There seems to be some interesting concepts in allowing for multiple versions of a single book with different peoples annotations in them. However, something that I thought about that is much more interesting. Due to the fact that our annotations change the text a bit, interjecting our own thoughts and ideas of this weird thing we are reading, is it possible for the /book/ to get edited by the person reading it? Is the possibility that I can read On the road by kerouac and change Deans name to my own, or change the inter-structure of who the characters really are to fit my own needs? If I change it enough, does it become my own text? Can I sell it saying I wrote it, will I go to jail if I do it? The article seems to point at copy right issues as an underlying ideal. Using this digital pubs what is copyrights anyway?
