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.

Agree-  no need to stall existing work.
