Alien Technologies is a non-publicly traded company. If RFID does face "explosive growth" are there any publicly traded stocks that would be relatively pure plays in that product area?

You may want to look at (publicly traded) system integrators, EPCIS "service providers" (look for those involved with pharma) and/or those companies that are directly involved with EPCglobal in helping to set the direction of the industry.

Personally, I would tend to stay away from investing in h/w mfg's at this point as these items could very well become commodities in short order and they could wind up getting the crap beat out of them in a price war with other mfg's.
