I don't think proxies and firewalls are going to be a major problem, like
Mike said, the myriad of UDP games out there seem to do just fine in the
real world. Sure, there will be corporate firewalls and proxies blocking
employees from fragging their colleagues when the boss is in a meeting,
but I guess they're partly put there to prevent just that so we probably
shouldn't try to combat it.
If we were talking about peer-to-peer UDP it'd be a whole new ballgame,
but that's why I specifically said the use-case was for client/server
games, I don't think we should attempt peer-to-peer before WebSockets is
all done and shipped.
I fully agree any discussions on UDP (or other protocol) shouldn't stall
the existing work, but right now there seems to be very little activity
