So I want to create two instances of SharePoint 2010 and a marketing microsite. From the Intranet, is it possible to mark some documents as internal vs external in addition to the taxonomy? How would this work securely? Would the documents that are external be published out somewhere? My use case: I'd like to create a folder called Product 1 for example. Some of the documents I upload to that folder are internal only and some will be customer facing. Of course customer facing documents can be accessed by employees as well. So from my microite and customer facing SharePoint instance I'd like to query all public(customer facing) documents, but I want to make sure inadvertently internal documents cannot be accessed. Is this common? It seems like it should be, so you don't have to keep duplicates of documents or have them in two different places. What is the best setup for this?
