REST + transactions paper

We've been working on REST+transactions for a long time now, with a number of iterations and implementations spanning over a decade. After various discussions over the past few months I'm hoping that a few new organizations (academic and industrial) will be coming forward in the near future to help contribute to this work. However, I think it's time we wrote a paper on this and got it published. We've got enough material and experience to target a range of conferences and workshops. Plus I haven't written a paper in a while: I'm starting to feel rusty!
