I was a participant in the Chromebook pilot program and I received a CR-48. When applying for the pilot program you had to agree that you wouldn't sell the device to anyone else (I don't know where the ToS for that is, but that was the gist). The terms implied that you weren't really receiving the device for "free", you were receiving the device on the terms that you will test it and provide feedback. I suppose it would depend on the ToS of the Google Glass pilot program, but I don't forsee Google smiling upon this as selling CR-48s was strongly discouraged by Google.
