I wasn't as rigorous about it as you around having a fixed schedule, but I applied similar principles: Avoid doing any work on my side project while at my regular job (unless it was needed by my regular job, e.g. on the open source front), and never let my responsibilities of my regular job slip or become a lesser priority. The real challenge here: running an infrastructure service as a side project is what nightmares are made of.
