I've contributed to a major derailing of the thread elsewhere. My 
apologies... To try to bring this back to your original point:

Andy mentioned that an HTTP/2 transport for WebSocket might mean that we 
could get rid of client-to-server masking. I don't have any data to 
support my spitballing, but that *could* be a pretty decent optimization 
for implementations, since they no longer have to mask or de-mask the 
data in place. For example, it might open up the possibility of 
scatter/gather I/O for frame handling?
