C-Saw's design demonstrates that coupling circumvention capability with censorship measurement creates a self-reinforcing incentive loop: users opt in for improved page load times, their participation grows the vantage-point pool, and richer measurements enable finer-grained technique selection per ISP and URL. The system avoids requiring a pre-populated URL list by building a blocked-URL database dynamically from user-initiated requests.

Implications
Embed passive measurement instrumentation (blocking-mechanism detection, latency logging) directly in circumvention clients so that every user becomes a vantage point — eliminating the need for separate, incentive-less measurement deployments.
Use per-ISP, per-URL blocking-mechanism records to dynamically select the minimum-overhead circumvention technique rather than applying a single universal method to all traffic.
