Is this possible? I have topics that I want to share in my own subsystem, but don't want exposed to external nodes because it's really not data that they should be using.

There is no way to limit access to a specific topic. For this sort of limitation a common approach is to isolate the network with the internal subsystem and run the "public" master and use some of the multi-master tools to expose the specific topics you wish available on the public master.

The topics will only be transferred to nodes that request them. If they are not requested, data is not sent. All this is handled by the rosmaster.

I guess my concern is a node can still request something that's meant to be "internal" data.
