I'm speaking a little outside my field of expertise

Oh don't worry about that. My professional field is IT. I'm just a space technology enthusiast that never got past algebra in high school. I recognize the difference between thrust and ISP and understand the different ideas behind forms of rocket proplusion, but I couldn't tell ya actual physics in mathematical form.

Thanks for the info though! It's interesting and an idea I hadn't heard of. Is there a good website for source information?

Do you post on www.nasaspaceflight.com at all? I lurk over there to keep up to date on the space industry.
