Are there some obvious grouping strategies that we can already consider? e.g., by PT, by bandwidth (lower bandwidth bridges sacrificed to open-invitation buckets?), by locale (to be matched with a requesting user's geoip or something?) 2. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges (and untrusted users have access to 1)? More? Less? theodorsm: 2024-10-24 Last weeks: - Adjusting to post-student life - Testing out beta releases of pion dtls and webrtc Next weeks: - Update Snowflake to use latest pion upstream releases - Test Snowflake fork with covert-dtls - Condensing thesis into paper Help with: - Feedback on thesis Facilitator Queue: onyinyang shelikhoo meskio 1.
