The only challange I see to this is the "edit wars" that often crop up between groups of editors. If you encourage a park to contribute their highly accurate and officially-vetted GIS data to OSM, where a local group may have already contributed not-so-accurate and definitely-not-vetted data, there can be some ruffled feathers. According to OSM documentation on their WIKI, the local users whom contributed the not-so-accurate data "trump" the NPS. Not sure how that can be worked around.
