With the return from GPU mining to likely be effected by ASICs, where can miners turn their machines? Should I become a pro gamer? Join a rendering farm for cash (do they exist?) and let disney use my rig to make toystory 4? Donate it to SETI@HOME or FOLDING@HOME? Donate it to an Anonymous botnet? Join a spamming farm used to bombard Bitcoin dev's with requests to switch double-SHA256 for double-MD5 in the code?
In short, what serious alternatives are their for profit or just putting to good use mining rigs?
