Right, as I wrote, I don't think that the author's intent was to use company time on the startup. All I'm saying is that the OP should be careful. If he has a long commute, that might work -- but if he has a short commute, then the line may blur a bit. It's almost good to have a solid chunk of time between working on work and working on a startup -- the possibility of confusion about the IP and about who's paying for what becomes increasingly remote.
