I am tasked with looking into using DNN to build a secure client facing portal.  This can be separate website or entry through a public facing web site.  Primary goals are to communicate with our clients with secure communication, let clients upload source documents to us, and for us to deposit, for client download, our work product.  No client can see any other client's files or communications.

On the wish list side of things, we would also like to be able to track of the activity from a centralized management console and since the information is confidential, we also want to encrypt all of this on the host server.

Can you suggest commercial modules that would get us down the road?  Any thoughts would be be appreciated.

Thanks for your help.

Oh Yeah.  I forget to mention.  Management wants this yesterday, there is no budget and I am supposed to work on this in my spare time!
