This blog post from Unity caught my attention:
I had already started looking at this Native Client technology announced by Google and trying to work out what it could be used for – what the advantages were – but the possibility of playing Unity games without a plugin and directly through a browser (admittedly just a Chromium build at the moment) seems pretty cool.
Now, if all the other browsers were to take up Native Client then we’d have a truly 3d game-friendly web and with Unity 3 right around the corner things would get exciting!
