Never used SharePoint then?
Has it's detractors but does all of the above perfectly well for us.
Up to 10 people working on a document at once, in-place document management (no more attachments sent via emails, just links).
For those of us who work in large companies (who are MS houses) and hosting on the cloud is not an option, does all that is required and a bunch more.
