1) The violator release their code under the GPL, as the license said they should have.
2) If they refuse my request for #1, I want to forget the matter completely and put it behind me.
If a lawyer offers to represent me pro bono and help me get the code, with no talk of getting paid, I'd accept that offer. I wrote the code with no expectation of getting paid for it. If a lawyer wants donate his labor to the project as I donated mine, that's fine with me. Otherwise, the lawyer can crawl up his own ass and die there. I'd rather have scenario #2 than see a lawyer getting paid to sue somebody over my code.
