+1 on finding ways to enable UDP. It's a key missing component to the
web
platform.
But there is so much infrastructure that would have to be enabled to use
UDP from a web app. How would proxies be handled? Even if specs were
written and implementations available, how many years would it be before
corporate proxies/firewalls supported WebSocket over UDP?
Agree - nobody said it would be trivial. There are so many games
successfully doing it today that it is clearly viable. For games in
particular, they have had to document to their users how to configure
their
home routers, and that has been successful too. If you talk with game
writers - there are a class of games where UDP is just better (e.g. those
communicating real-time, interactive position and other info). If we can
enable that through the web platform, that is good.
I am all for finding a way to get datagram communication from a web app,
but I think it will take a long time and shouldn't hold up current
WebSocket
work.
Agree- no need to stall existing work.

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
anyways.
