I think using rpc for file access is a bad idea, it makes only sense for
management stuff.

I think it would be better to use the trans2 (or was it nttrans)
subcodes, to implement for cifs proxy. Your aim for the whole project is
 performace, so should really do it at the SMB level.

Note: you can still use ndr encoding for some sub-opcodes content,
but for read and write you should avoid it.

Also note there're known bugs in our dcerpc client code,
in the handling of broken connections.

And the dcerpc server code doesn't support async requests
via the smb transport (ntvfs/ipc/).
