I too was quite surprised that there are not more commercial users of PI. Maybe we need a more organized attempt to spread the word, perhaps on a country by country basis.
I see that there are some of you making presentations to various astronomy clubs and institutions. A means of sharing these with interested users might help. Maybe a common registry of available presentations.
All I can say, Juan, is that you have a very good thing going with PI, so be sure to let us know how we can be your "distributed sales team!" (And stay healthy, please!)
