@James, I'm not working on ATS project at Taobao now, and be busy with another project.
I hope you and other developers can continue to improve SPDY/HTTP2. The probe mechanism and configuration will be easy to refined, patch is welcome. Moving from TS API to the internal API(IIUC, that is removing the dependency of FetchSM) needs more hard work，and I don't think it's more urgent than introducing HTTP/2 to ATS. I believe that the supporting of HTTP/2 will make ATS grab much more market share, that is really very important for this community. So, I hope our community can go on to refine SPDY/HTTP2 patches, so that it can be landed as much as quickly.
