After doing more research, I pretty much answered my questions myself. If it helps at all, I can definitely say HTTP/2 seems to be working with Google Chrome v40 and Traffic Server v5.2.0.
I ended up tracking down the Google Chrome flag and enabling it early...before Google ships their change. :) It's pretty nice, and seems to work well. Facebook and Google sites at least load a bit faster, although it's really too bad the browser developers have opted not to implement plaintext HTTP/2 just yet. Best of luck with the relevant changes for Traffic Server! Regards, Adam
