Greenie my love...
despite the fact that I'm often unsociable and unreachable I think you're worth millions. The amount of information that you've shared with people over the years for free has been more than generous. If they don't know who you are the reason why should be perfectly clear. There are those who are part of their little network of circle jerks and monopolistic video clan and those who are not. In that respect, I would consider you the king of "the other".
If you choose to share at Internext do it because you have something to say. Id decide what your minimum is then ask for 4 times that. Decide in advance whether the exposure itself is worth your while then go with what you feel isnt exploiting you. I personally think that you're MORE than necessary to make the panel worthwhile.
Much love!
