With experience as an entrepreneur and system engineer, I think you would fit a senior position perfectly. Don't you think you could teach a thing or two to younger ones? :-) Otherwise, I'd suggest pushing daily code on github to show that you still enjoy hacking and can get shit done. That would be my biggest fear.. Is he still passionate about coding and debugging stuff? Also, saying that you are an entrepreneur can be a bit scary for some employers.. They know that you could leave on a heart beat to start a new business.
