[mosquitto-dev] Subscriber list

[Romu Hu <huruomu@xxxxxxxxx>]

Hi,

Is it possible for mosquitto to provide subscriber list to client? For 
example, to get the subscriber list of a topic, the client subscribes to 
$SYS/broker/subscribers/[topic], the broker sends the list to the client.

Any hint on how to implement this in mosquitto?


Thanks
Romu
