[B.A.T.M.A.N.] batctl: feature to filter nodes/clients

Hi,

I need to display the number of all nodes/clients as well as all neighbor nodes/clients.
This would be easy if batctl would be able to output the respective
list of mac addresses (batctl ... | wc -l).

I've started writing a patch as part of a feature request:
http://www.open-mesh.org/issues/203

But the problem is how to get the respective output form the debug tables.
I have been reading the docs, but have not been able
to understand the necessary information needed, no offense:

http://www.open-mesh.org/projects/batman-adv/wiki/Understand-your-batman-adv-network

Some explanation beforehand:
Clients are computers not running batman-adv,
represented by the MAC address of its network interface.
Nodes are computers running batman-adv,
represented by the MAC address of its primary interface.

List of all nodes:
Get all MACs from the 'Originator' column of the originator table

List of all neighbor nodes:
Get all MACs from the 'Nexthop' column of the originator table
and make it a unique list.

List of all clients:
Get all MACs of the 'Client' column of the transtable_local table
when it starts with a '*' character.

List of all neighbor clients:
Get all MACs of the 'Client' column of the transtable_global table
when it starts with a '*' character and when the nodes own originator
MAC (of the primary interface?) is also in the 'Originator' column.

I do not think this approach is correct, yet.
Maybe someone can drop some hints.

thanks,
mwarning
