Similar to video compression which uses key-frames and differences between them: every N publishes we send a full report, but inbetween we only send what has changed. Fairly simple approach in the probe - hold on to the last full report, and for the deltas remove anything that would be merged in from the full report. On the receiving side in the app it already merges a set of reports together to produce the final output for rendering, so provided N is smaller than that set we don't need to do anything different. Deltas don't need to represent nodes that have disappeared - an earlier full node will have that node so it would be merged into the final output anyway.
