To expand ethanol production to a truly useful level in the United States, these other, rougher sources of fermentation—which produce what’s called cellulosic ethanol—are essential. “If ethanol is to be a significant solution to our transportation needs,” said Alan Greenspan, former chairman of the Federal Reserve, “it will have to be cellulosic.”
Up until now, however, low yields and high costs have made cellulosic ethanol a commercial dud. Then, a few years ago, a small company called Celunol Corporation, based in Cambridge, Massachusetts, licensed a handful of patented genetically modified bacteria developed by scientists at the University of Florida."

We've big companies going into cellulosic ethanol in Finland. The first pilot plants should be running 2008. The rumour goes that we are advanced in this field. Time will tell more about the productivity, yield and total cost of operations.
