On the one hand there are tons off applications that don't need UDP and will do just fine with WebSockets. Lots of AJAX based sites can be made much more responsive through WebSockets. Email sites, sites like Google Docs, etc. Chat sites like Meebo or Google Talk. Even many types of games will do just fine with WebSockets. A WoW style game, a Diablo style game, etc.
On the other hand they, the w3c and the browser vendors, are working on unreliable (ie, UDP) peer to peer standard based off the WebRTC stuff so for those applications that can tolerate the unreliableness (ie, voip, video and real time games) it's not far off.
Thanks! I didn't know about WebRTC, so this seems like good news. Is it tailored to video/audio or are we talking about something you can design a protocol on top of?
