openlearn is a massive effort from the UK open university to make their course materials free and open on the web. You can also remix and upload your versions. See the openlearn talk @ the London Knowledge Lab.

Also, check out the OpenLean2007 conference (deadline coming up!). Free open content & a free open lunch.
