Note a websocket indirect bouncer instantly hits the connection limit without any sort of webirc protocol attached. java applet if it isn’t properly signed the user has to jump through hoops just to get it to run. Flash atm all it takes is editing the policy file itself and how it is handled depending how they have that setup for both video and chat. And if they want more security they could then add some sort of webirc protocol that way an app can be tracked rather than the users.
The latter is “easy” for them where the pure websocket server that this OP was about is changing a lot of the back end. And I understand that they may be looking at it but the constraints right now are more about the features some team wants like I seen the vote function floating around in some chats here and there. That is a really cool addition to the ircv3 that they’re working on right now.
