Hg supports multiple protocols to access repositories. For developers, the main one is ssh:// which allows for cloning, pulling and pushing. HTTP access is R/O by default but Hg now supports R/W through https.

Most developers use the git+ssh:// refspec, which uses ssh as the transport for both fetching and pushing. Most users use git://, which is a custom protocol that isn't secure. We could export a tree using https://, which would be safe but slow.

This might be an area we would need to improve: provide a gits:// that was SSLed but also fast like git://
