One of the things I wish browsers supported would be signed content... IE your CDN&#x2F;distributed content doesn&#x27;t need to be on HTTPS, just have a header with a payload signature against the HTTPS cert that the application host uses...  I don&#x27;t know why such a beast was never introduced into the browsers.<p>I also feel that it would be nice to see more p2p protocols especially regarding live chat, and other systems.  I think having a self-discoverable alternative to IRC could be a pretty nice thing... of course eventually the bots would destroy it if it got popular.
