Custom topology and addressing

[efsantana]

I want to create a network like this.

Based on the docs, it seems that the network can only have 5 levels and follow this addressing structure:
Node 00 is the base node.
Nodes 01-05 are nodes whose parent is the base.
Node 021 is the second child of node 01.
Node 0321 is the third child of node 021, an so on.
The largest node address is 05555, so 3,125 nodes are allowed on a single channel.

But I want to have my own addressing and levels, is it possible? How should I proceed?
