I did the same recently, you can already leverage transducer support in core.async while staying backward compatible with clojure 1.6. You loose some sugar and the transducer versions of most sequences functions but it's very usable still.
you can see 2 examples here: https://github.com/mpenet/jet/blob/master/src/clj/qbits/jet/client/http.clj#L63-L84 one just decodes chunk from http responses as they are fed to a channel, the other takes every chunk from the response and reduces them into a single value before putting it into the channel. Not a killer use for sure, but it makes code a lot less convoluted.
