I couldnt find the details about how they are going to capture data.  Is it by Hams manually capturing files and then emailing them in?

At first blush one would consider having all the APRS ground statis be IGates and send it all in, but that will not work, because the APRS Internet system (APRS-IS) filters out all dupes and only forwrds one copy.  So when 20 statiosn receive the same thing (desired for this experiment) only one copy makes it through the internet.

Maybe they have a different plan...

But otherwise an interesting expriment.
