Mirage,

For that particular issue the description is very broad.

Can you please provide mode details (or example) on that issue?
Is it like adding CRDT data change events for a same node? or between nodes?

I was assuming it was adding change event to a single node.

I would suggest that you gather the requirements and figure out what to do.

1) Look over the gossip code
2) Look other tools that implement pub-sub
3) Make a design document (text, images etc)
4) upload to jira ticket/wiki
5) ask the community on this list for comments

I can help where needed, but I don't want to dictate what needs to be done,
for an issue this part part of the process is community based discovery.
