I think we need some kind of crazy new hardware. Crossbar tech or memristor for example.

I noticed the Yacoin.org page doesn't encourage much investor confidence right now... If you really want to put a warning up at least keep the links to the forum and block explorer.

 I originally suggested a coin that gets more memory hard over time as a concept sometime before Yacoin was developed.

To beat the botnet we need some crazy new tech. Perhaps something like this? http://www.crossbar-inc.com/products/3d-rram/

So Beave don't sell your house... I would suggest crowd sourcing the money required to buy some high end tech for mining very memory hardcoins and then selling mining shares.
