This problem has concerned me for some time. One solution would be for websites to declare their license (Creative Commons, proprietary, public domain, etc.) and then web pages can embed the content of pages linked to when the license allows it. A web with content-based addressing and versioning built into the protocol could also deal with this situation more gracefully, but again there are copyright issues.
