In response to Kaido's long post about structure, I can get that. I would definitely need something like that too.
As I mentioned the past year I was working as a cofounder of a startup on a mobile application. I put in 20-30 hours a week on it outside of my normal. So it wasn't like a couple an hour week type of thing. I typically get up for work around 5:45am or so, sometimes early, and leave between 6 and 6:15. Some days when I get my haircut, I would get it cut at 9 and leave the house around 8:30 or so. Those days I would get up at my normal time, usually around 6am, and do work until 8:15 then get ready for work. I would literally wake up, piss, walk into my "office" with my eyes still half shut, put headphones on and fire up Pandora, and get to work. So I have no problems with doing that.
Also as far as team collaboration, I still did that with the developer I was working with. I chatted with him daily. We'd get on screen hero often to talk over issues and walk through problems. I've noticed people mentioning a lot of tools I've used in these listings.
That said, I'm just at the exploring opportunities stage at this point so it's not even close to becoming a reality. I don't know if I would like it full time for a long time or not but there is really only one way to find out. I can say for sure I would love not having to commute. I also have no plans on building a home gym, I don't want to work out at home I want to have to "go to the gym" to do so. I've always felt that way and have no plans on changing that.
