Way back in May 2006, David Jakes authored a blog post about what factors contribute to sustainable innovations (i.e., technology and pedagogy) in classrooms. These include institutional readiness for change, multiple entry points for novices and experts alike, value added and invisible technology.  Take a quick read. Take a look at some of the comments as well.

Do these still hold true today? Would you add others? Would you replace some of his?
