I saw that in your article a bit :) But Yahoo Pipes for me was about relatively effortless web infrastructure for me. A self-hosted solution would only be close enough to that if it was a one-click heroku image probably, and even then that would be problematic, since my account uses their free plan already for something else. That's a big part of why I went the SaaS route with my Pipes adaption and added self-hostability only later.
