Attached is a BETA version of a new WeDo plugin that supports multiple devices. It follows a schema similar to what Alan proposes above. I only have one device, so it is not tested for multiple devices, however, it seems to work for one device and includes a new feature which tests for devices before each start, rather than just at launch, so devices and be plugged in and unplugged without having to restart Turtle Art. Feedback greatly appreciated. regards. -walter -- Walter Bender Sugar Labs http://www.sugarlabs.org
