In our `bridge-stats` file we currently have `bridge-ips` which tracks the number of connections per-country, and `bridge-ip-transports` which counts the number of connections per-transport. Still, these two data points don't allow you to infer the users-per-transport-per-country; which would give us useful information in case of blocked transports in specific jurisdictions, etc. gamambel today suggested that we add such functionality, which seems like a marvelous idea. `wfn` and `grindhold` seem interested in coding this. As discussed in IRC, interesting functions here are:`geoip_get_transport_history()` `geoip_format_bridge_stats()` `validate_bridge_stats()`. We should also define a nice format for this new line in `bridge-stats`. A not nice format is: `bridge-ip-transports-per-country cn::obfs2:42,obfs3:46 ir::obfs2:10,obfs3:666` we might be able to find a better one (or even one that is used currently somewhere else in tor).
