Like other posters I'd advice to say 'no'. I'm on the other end of the scale as I took such project knowing I'll have not enough time to work on it and now I regret making this decision. It's more difficult to drop it now that it's 'almost finished', and more importantly because of people I built it for. Sure, I got a % of venture, but any % of 0 is still 0.. I'd prefer to have clean mind over weekend and spend time with kids than worrying about stuff that needs to be done.
