Wow-thanks, guys for all the info. I am more surprised to have not heard ANYthing regarding this (no matter how difficult or "pie in the sky") and can agree that while it does seem like looking for the holy grail, I'm genuinely perplexed that there isn't more intelligent (non-hype)information. It seems to me that more than a few times progress has been made by re-looking at "proven unworkable" solutions.
