> The difference is this one plugin is capable of covering much more ground than Unity3D alone. Once it's there, nothing stopping one from porting, say, id Tech, Unreal, Frostbite, RenderWare, OGRE, Avalanche, Crystal, CryEngine, EGO, Source, etc. to NaCl and running it in the same plugin.
That's already possible with the Flash plugin using Alchemy. There are demos of several of those game engines running in it.
It is also possible to compile those technologies to JavaScript and run them without plugins at all (using Mandreel or Emscripten), but the experience would be less uniform (results would be different in different browsers), which is probably why it hasn't been done yet.
