Had a meeting with the CETS (something like "computing services" or "CS facilities" in CMUese) about potential applications, which was productive. I think I may have figured out a new super-nice no-logical-relations proof technique for showing metric soundness of the type system that may be amenable to Twelf proof, even. It's interesting to me that the technique seems very blatantly not to generalize to something that would let you get rid of logical relations for describing contextual equivalence, which means exactly that I think it has a chance of working.
