I've managed to work out that I need a populated and valid
 struct dcerpc_pipe *p
but there's a lot of different functions for opening rpc connections to
choose from, and I'm not able to prefer one over another.

I guess the proxy backend will open an rpc pipe for every tree_connect
that occurs, and use the pipe for proxy specific transfers.

This suggests to me that the users credentials can be used when opening
the rpc pipe, although I'm not sure if it is any better that using the
machine credentials, as I will be recovering and passing the clients tid
in the context of any rpc calls anyway.

Please could you advise me on the different rpc pipe open calls. I will
want to be doing syncronous and asyncronous calls in both directions? 
In short I know my uuid...

I'm still looking, but a hint would be very much appreciated.
