I could imagine something like this working, but it would have to be:

 - Trusted (code, idea, prommoter)
 - Open (source, info, community)
 - Wide (participation)
 - Cheap (no fees or close to none)


Guive me all of the above and i'm game;
I believe a lot of people would participate under those conditions.

A newbie-promoted, mostly obscure lottery? Nahh - i'd rather keep my 0.1BTC, thanks
