This looks pretty neat. One thing that would be really cool would be support for event logging of protobuf messages. Some way to provide squizy a protobuf bin file that describes all of my messages or something and then a way to generically send you a bunch of protos and have your api serialzie and allow queries and notifications based on these messages.

One thing we have at work is something that's like this:

    message Event {
        enum type {
            UserLoginFailed login_failed
            SpecificApiRequestMade api_request
            ....
        }
    }

Right now we're turning these protos into json and serializing it into a mongodb for easy queries. This way we can do things like "COUNT(*) GROUPED BY login_failed.username" and find accoutns that are being targeted by bots, for example.
