Here is something that should be right up Poets alley. Now I noticed that Ayer Labs is one of the guest speakers on that day. I went to their website. Looks like they are working on a similar solution as I am sure others are as well. I dont know the cost savings or efficiency. Anyone with more knowledge care to have a look? Comparison ?
