I imagine the Koch Brothers follow through on their commitment to "ban the box" (http://abcnews.go.com/Politics/koch-brothers-donors-ban-box-...) and not ask about felony convictions in job applications. There are other companies operated by executive teams from across the political spectrum that probably do the same -- maybe you could be hired by one of these companies (?) .

Software systems at times touch sensitive info, and it might be harder to justify hiring a formal felon to work on these (might depend on the nature of the crime), so YMMV.

Good luck to you, I hope you continue to sort out your issues and that you good way to support your family.
