Thank you ARomeo for the response.
The Document referenced is an excellent resource for VMware Tools, Content Library and a good many other things, but it does not appear to talk about how to combine Content Library, ProductLocker and VMware Tools to create a single storage location for all 6.5 / 6.7 ESXi hosts / multiple vCenters, to standardize on one version of VMware tools.
This is something I read about some time ago and am looking to implement. I am still looking at the document - it is rather large - but so far have not found any direct reference for what I am trying to do.
Any other resources?
