You release nothing. You copy every algo that Epsy has released that you put in "your" miner.
I relased Skunk sp-mod #1 before there was an opensource ccminer implementation of skunk. My release is not even based on the same repo as Epsylons fork. My release was very profitable for the donators. The first buyers should have roi'd many times already.
Actually, since your "release" (private selling is not a release) is from my publicly available fork, it
is based on the same repo as Epsylon's fork.
And for skunk, all that it was missing was a scanhash function, which anyone could reproduce by copy/pasting another simple algo, pretty straight forward procedure.
All the kernels are/were there.
