Long story short, I am writing a new ALSA driver that supports compress 
offload. The only user land support I could find is in tinycompress. I 
was looking at adding gstreamer support to facilitate my testing and 
hopefully make the driver more useful.

I am happy to use tinycompress if that's the official way alsa wants to 
support userland applications. When Takashi suggested that he didn't get 
patches for compress API support in alsa-lib I thought it was a hint 
it's a better idea to have it there. I think it makes sense to merge 
tinycompress into alsa-lib as this will make the functionality more 
readily available - if license is not an issue.
