ethanol as fuel only makes sense when working from cellulose instead of starch (or cellulose + starch), because the feedstock for the ethanol production is far cheaper and has less alternate value.

I didn't check out the link that deserth provided, but i have a friend who talks about E85 quite a bit, and has sort of collected the analysis of it including re-sale cost of process byproducts and so forth. He sent me a link to a website of "pro-global-warming" scientists that gave a pretty good essay on ethanol and how it could be made to work within 30-50 years. i'll post if i can find it.
