Hi Don - I'd take Chris up on his offer in a heartbeat - I was having a discussion with one of my Geology professors just last week and was discussing your track record - she asked me what your methods were and I had to shrug my shoulders - I then got a lecture on how important it was to share data and info in science - that's what its all about.

Publishing a paper is the way to go and Chris knows the ropes so you can't ask for a better opportunity!
