Motivation

• It shouldnt cost you to give content away.
• The Internet Archive has 300 TeraBytes of free
  content (web, movies, audio, books), some of
  which is hugely popular.
• We need to augment the infrastructure of the Net
  to efficiently make popular content accessible.

Policy Challenges

• What is popular? (Count requests.)
• Where should copies be kept? (Closeness by IP
  number network topologies.)
• For how long? (Least requested or oldest out
  first.)
• Avoid Tragedy of the Commons (1000 hits from 1
  host should not outweigh 100 from 100 hosts
  temporarily block IPs.)

Technical Challenges

• Correct browsers are all alike.
• Every broken browser is broken in its own way.
• (To paraphrase Leo Tolstoy)
