looking toward the future is already incorporated in a low to mid $$$ appraisal IMO, because the current usage potential is basically zero. I think many people might be overestimating the value of every possible acronym for something. Also the success of this technology is questionable, some people think it will get bigger, but that does not actually mean it will, 10 years from now there might be something totally different in the pipeline. I think if you actually have a low $x.xxx offer that is already worth consideration. Waiting for 5 figures I think does not make a lot of sense, and nobod knows whats going to happen with this technology. I actually think a good time for selling is now as the talk about global warming is peaking IMO, thats always a good time to sell.
