[B.A.T.M.A.N.] How to send message/execute script on clients from Gateway?

Hi,

I would like to know if batman adv [2013.2.0] supports a way to send/receive message between gateway and client?

I have setup a mesh network which has 1 gateway and several clients. I want to broadcast a message to all the clients from the gateway. The message might contain one more many parameters that I want all clients will use these parameters for their configuration.

It would be very convenience if I could execute a script remotely on clients from the gateway via batman adv without knowing their IP address.

Thanks, Dat
