I see idea, Andreas.

Igor also have told me that he have got idea how to use policies for packets
in client-server. We have not discuss this yet. But he think about issue
here.

But we talk now about Tree of Nodes.
This can be 10-20-30 nodes.
To send them on server we simply need make protocol for them.

By the way, you have some ideas for RPC implementations?
For now we simply build packet for each operation we need send on network.
