I wish that I had something to suggest that did not have a positive and a negative. Family issues can be very difficult to deal with personally and even more difficult to deal with as a third party, because you can never know how others might react.
I would personally work with him, if you think that you can deal with him and that he won't leave you out to dry within a few months. Keep the final goal in sight. That is what others have told me here. And if your final goal is to work on these things full time and to fund it, money is going to make that possible.
I would not worry about being "given" something like this. Regardless of what you might think your father thinks of you, the reason he is asking you to work with him instead of someone else is because he sees something in you, and that is earning something, in my books. In my experience, even with family, respect was never something I just got because I was their son. It is something that I needed to earn. Tough, but the real world is like that too. And I say this even in spite of the current hand I've been dealt, leaving me about as low on the totem in my parents' eyes as is possible.
I guess I have given a little bit of advice, but make sure you look at it just like that: as advice. I wouldn't leap just because me or someone else thinks you should. But don't toss it out, either. In the end, the decision is yours alone.
Let us know how things go. And if you're making millions someday, send an H1 my way, okay? It can be a beater, I'm fine with that.
