First of all, I think GameFS is awesome and I'm going to use it in Wizard Arena (which unfortunately has suffered a few setbacks due to some unforeseen problems). I'm curious if there are plans to expand upon what GameFS offers in terms of having your whole game stored on the system and just letting the loader spread virally. I'm thinking of what Mochi does with their Live Update service. When a user uploads a new version of the game to their servers, the viral version downloads a small patch instead of downloading the entire new swf. That patch system automatically works using a byte array of the original, and the loader loads the differences between the original byte array and the new byte array, and then patches the original byte array, and then adds the loader object to the stage.
I was thinking that if GameFS could be expanded with that functionality, it would become even more awesome than it is now. It would be really helpful for something such as changing the wording in a menu, or other minor changes. That way the entire swf wouldn't need to be downloaded each time because for games with a fairly large file size that becomes somewhat cost prohibitive.
Cheers,
Mark
As a side note I think it's wonderful that the Player.IO feature set is expanding while the base pricing is staying the same.
