Getting HTTPAPI to accept compressed streams is not hard at all (just add some parameters to the HTTP request). I don't recall that I got to a point where I could decompress the data.  If someone was good with APIs and integrating UNIX software, it shouldn't be overwhelming to build the support for one or more compression algorithms.
