Why do I need a URL?  Do I really need to a location?  Why can't I just enter a set of keywords, like I do using Google, and just drop things into the page to share them with others?  That would allow me to store instructions on how to sew socks at "101st, Easy Company, Christmas, Socks" and allow anyone in 101st to get at it including Easy Company.  What happens in the background is that a set of P2P data services respond to the set of keywords and volunteer to store whatever data I throw into the browser window.  More on this later.
