Goals:
1. Ensure network scales by being user or usage bound, as opposed to bandwidth growing in proportion to network size.
2. Staying with in a reasonable bandwidth limit for limited data plans.
3. Do the above without materially impacting existing nodes.

NOTE: Traffic extremely sensitive to bloom false positives
This completely dominates network traffic at scale.
With p=1% we get 10k users ~100MB/day and 1m users ~10gb/day)

Next step up is to either only use contact code, or shard more aggressively.
Note that this requires change of other nodes behavior, not just local node.
