I can see a couple of approaches that could work to limit the sending of 
unwanted data.

One is to subscribe to QMF event messages to detect binding and 
unbinding at the sender, and deduce from that whether it is worth 
sending anything.

The other is to have the receivers explicitly send control messages 
themselves indicating when they want and when they no longer need 
particular data sets.

Of course a lot depends on the nature of the data.
