I've also compared performance to the Cortado Java applet we currently
use -- Cortado is still a little faster in terms of CPU usage, but getting the applet to actually *run* with the current version of Java is a nightmare -- even the signed version of the applet from theora.org requires adding a security exception -- whereas JS or Flash "just works".
For the curious, i looked into the java applet a while back. The reason the caortado applet from theora.ogg doesnt work without a security exception is that they signed it wrong. It needs to be signed and an attribute set saying that it doesnt need extra privs. That attribute isnt set on the theora.ogg version. Even then it still needs a click through prompt.
Anyways, great work on all this.
