My total speed of 600mill/sec was spred over ~20 different computers including friends and family.
The power consummation on todays cpu is not that bad. My laptop Core i7 has a max TDP of 15w.

Lets play with some numbers.
My fastest PC did 46mill/sec. (a Core i7-6700 @ 3.4GHz)
Say we as a group can collect 90 of them
That should give a speed of ~2^32 / sec
After 12 days we would reach 2^52 iterations.
If we are as lucky as I and solve after 2^50 iterations then this would take only ~3 days

Some other attacked this curve before I did and implemented it on FPGS's

If I where to release a product today then I would not rely on a 113 bit's koblitz curve. Using a different 113 bits curve would be a bit better and perhaps out of reach for reversers today but new cpu's are hitting the market as we speak and the new inlet with 18 cores and amd with 16 corse will probably be speed monsters.
Would also be fun to try implementing this on GPU.
I know they did some research on this when attacking ecc2k-131.
