 thanks and we look forward to your contribution.

 There is an assumption to some level. We do trust the ipaddress (got via
tcp connections assuming its difficult to forge) and we use
Raw tcp (so no security in the transfer layer). We do have a authorization
layer that is pluggable at the server and the clients can identify
themselves using that.

Its still in discussions. We don't have a conrete proposal yet. For multi
tenancy we don't need to consider it.
