Mike,

My reading of the spec is that you can return a callback instead of a
body, and the Plack server should handle the rest:

https://metacpan.org/module/PSGI#Delayed-Response-and-Streaming-Body

If the server doesn't suppport streaming, a MiddleWare can provide it:

https://metacpan.org/module/Plack::Middleware::BufferedStreaming

I have not needed to do this yet myself with PSGI (but will eventually).
