One thing I would love to see would be an app version of wizard 101 for Apple TV. The new apple TV allows downloading gaming apps, and includes an interface for skylander/disney infinity.
KI could develop a similar platform interface, with couple 'generic' character tokens, with possible buyable character forms on the site. The token would contain the character information in the token base, removable to allow you to upgrade the character form on the token.
The tricky parts would be to figure out how to work multi-player would work with the current code base, and to ensure authentication if Wizard 1 and Wizard 2 have separate accounts, but want to play together. (Family play night, ect)
