Unity web player plugin for mobile browser

I think that's not possible, cause otherwise there would be no point for unity3d to have iOS,android or other mobile mobile versions.

you might wanna check cloud servers. Using that technology is even possible to run maya on a ipad or anyother tablet. http://www.youtube.com/watch?v=e3cCMVDdZ9A

The point of playing in web player is meant to not install the game. For 'easy' games could work fine, but for proper games you definately need to install the game in your mobile...

Actually, it's also impossible if you install the webplayer build on the pone. (The webplayer folder with an html and an unity file. It just won't open).

I hope they make it compatible in a future release as I don't believe it would down-grade the value. You wouldn't be able to sell it in the Apple Store, and the performance would be slower as it would still be running in a browser.
