Hi,
I just found out about this via the unity forum and wondered if it may be of interest for the future of game editor and a possible web player:
http://code.google.com/p/nativeclient/
http://www.gamasutra.com/blogs/MarkDeLo ... _Store.php
It is used for embedding applications and games into web pages without a plugin. (so far only on chrome but it is open source so other companies may adopt it too)
Cheers People,
Marc
