Hello -
This sounds like a really interesting idea. Unfortunately, it sounds like your application would require the Cius to be in USB Host mode
(http://developer.android.com/guide/topics/usb/host.html). USB Host mode is only supported in Android 3.1 and higher, and the Cius is currently on Android 2.2.
Please check back on this site for information about future Cius upgrades.
Thanks -
