Well, this is a start, but it's short term at best: To Cut Textbook Costs, They’re Printing Their Own: "On Wednesday, the Arizona community college announced a partnership with Pearson Custom Publishing to allow Rio Salado professors to piece together single individualized textbooks from multiple sources."
I think schools would be better off collaborating with each other and producing content in a wiki, exporting to .pdf and uploading to Lulu.com for a lovely hard cover text for a fraction of the current cost. Do profs make money writing texts? Not very much. So we have an industry that is where music was a decade a go: end-users who feel violated and abused and producer base where only a few see strong financial rewards. And the mediator (record label, or in this case publisher) does make money. How long can a business survive if they have completely upset their end users? And not rewarded their content producers?
