>>Oh my....I could dig up some email exchanges we had on NoSQL back in spring 2011 - but hey, let's not bring up old battles. :)

Old battles?! No recollection of any battles, let alone battles about NoSQL. Seems to me that for the most part healthcare data needs are relatively simple (though bulky) so arguments about database often have less to do with customer need than proponent familiarity. I can tell you that a very large and successful US vendor has products based on MUMPS that was NoSQL for decade before that label du jour existed. MUMPS (Massachusetts General Hospital Utility Multi-Programming System) started in 1966, is basically agnostic about memory vs disk-resident variables or data collections (sound familiar?!) , has several open source variants apart from the dominant Intersystems Cache, and survives because customers want it to.
