Be aware that you're risking your rep over here. 101 things can go wrong on launches. You know that.
Even PA will have huge impact on your reputation. People will blame you for anything, even it's obvious it's not your fault.

Do not share source with pool owners before launch, because there's always that 1 idiot who'll fuck up. Talking from experience.

Anyway, once more. Good luck. Waiting for the launch.
