As I understand you can use Aware IM for documentstoring, right?
My wonder now is, how are the documents stored, in a filesystem or in the database?
I hope the answer is filesystem!
We use Sharepoint today, but it has the disadvantage to store everything in one big database (which is impossible to access from outside). So if something happens to Sharepoint (which it ofcourse does, often..) you can not access the documents.
If they on the other hand were stored on a filesystem it would be much easier if something happened.
