So, I've found media blurbs via Google and here referring to "document management" with ZCS but I have (so far) found virtually nothing on how to make this work. Further, outside of hosting documents that are supposedly shareable via the web client I haven't found anything that speaks to Outlook, or similar mail reader, integration.

The issue is that we have three clients in our pipeline - some 3,500 seats total - that are asking us to provide some sort of integrated solution, with ZCS as the mail engine, that offers "Sharepoint-like document management".

Over the years I have learned that if Microsoft can do it, Open Source can do it better. I just haven't found out how to do it with ZCS as the core yet.

Any ideas? Thanks!
