Perhaps instead of doing this in-core it would be better to make log handling more extensible? I'm thinking add a specific "binary" format and an external tool that can parse that and do whatever the user wants with it. That means we don't have to keep adding more complexity to the internal log handling (which already has the risk of being a bottleneck), while allowing maximum user flexibility.
