Sorry for my English.

I saw some launches of CPU coins and it seems that after 2-3 hours after launch botnets are starting to mine this coins. No matter of code etc.

It seems that Eth can be target of such networks too.
512 MB per thread is not too much  when I can usually see that my Firefox is eating 2GB easily. So 4core CPU can be used without much trouble to user.

Will be our GPUs usable or not?
