Great, I will get myself a webcam ;-)
Looking at my schedule and the time difference, it would suit me best to
have the discussion in the afternoon, Portland time. Any of the days are
fine with me.

AFAIK websockets itself nor the JS APIs mandate any fallback mechanism,
so we are free to use whatever we like. And we happen to like BOSH. ;-)

Appr. 2 years ago Stefan Strigler did some benchmarking with the
experimental support for websockets that was added to JSJaC
combination with the preliminary support for it in eJabberd. Compared to
BOSH in the same combo, it was remarkably fast. If Steve still has his
benchmarks around, it would be nice if he could step in here...

I assumed that the changes to the websocket protocol in the last years
would also need an update of the XEP, probably that assumption is
incorrect. But I would like to know for sure.

Thanks, that would be very useful.
