I think remote is quite realistic if you have decent chops. It's the part-time that will be problematic. Nobody wants to hire part timers. Most places aren't even happy with 40 hours a week. I work remotely (9 time zones apart!), but I find that I spend at least 2 hours of my day on communication. Since I'm fairly productive the rest of the time (6 hours), I can more than make up for it. If you were only working 3-4 hours a day, I can imagine that in many circumstances it would be a struggle to be productive. Having said that, there are some teams who are super organized and can just ship off short stories if you are an amazing coder. They are few and far between, though, so you will really need to network to find them. Good luck!
