Thank you, Tod.  Yes, I MIGHT find a VERY SELECT SUBSET of these data SOMEWHAT 
useful, as minor amounts of them seem to be accurate and more-up-to-date enough 
to introduce into OSM.  But certainly not using any sort of automated method.  
Essentially, every single datum would need to be human-reviewed, possibly 
corrected, likely conflated, and for a great many of them, on-the-ground 
verified.  I'd say "garbage" seems too strong, but "very noisy with a highly 
limited potential to add some minor value to our map, coupled with great effort 
to vet, improve and enter the data" seems about right.
