Opportunities for Samba4 based CIFS proxies

[Andrew Bartlett]

With the work I now have in the Samba4 tree, we can now operate as a
CIFS proxy, potentially modifying the data stream in the process.  We do
so with the administrators permission (based on kerberos delegation),
but it does open up an interesting area of research for somebody wanting
to construct:

 - CIFS virus scanner
 - CIFS accelerator
 - CIFS aggregation server

etc.  

We already have the full mapping of CIFS down to the ntvfs primitives,
and we know we pass the full semantics down those layers.  More
importantly, using kerberos we support full SMB signing of both halves
of the connection. 

It should not be hard to build some interesting products on this basis,
and I would love to hear form anybody with particular ideas.

Samba4 also includes an RPC proxy server, which will be hooked into this
soon.
