This will be very useful! Thanks from me as well.
I had heard, from MIT I think, that there is going to be a p2p version i.e. Universities would have open servers with hard-drives full of their own papers and those downloaded by its own researches from other universities.
Two projects that would take the internet back to its roots, imagine, once again, being able to search the web for knowledge without any commercial noise. Ahh bliss.
