InputStickProxy application will allow Android phone to act as a proxy between PC and InputStick. This will allow to send keyboard and mouse actions from PC to another USB host:
PC <- (3G / WiFi) -> Android <- (Bluetooth) -> InputStick <- USB) -> USB host.
Using InputStickProxy will be much easier than implementing direct support for InputStick on PC. Also, limited support for BT4.0 on PC platforms will no longer be a problem.
More info soon.
