If there is demand for it I can write a simple mobile application for symbian mobile phones. This would allow to display the actual playlist or to remote controll the empeg. This application should run on any symbian enabled smartphones. (mainly available from nokia)
Another possibility is to write a java application, as java is now supported on most of the new mobile phones. But the experience shows that mobile java code does not work correct on all java supported phones, particularly regarding bluetooth support. (The mobile needs at least to support jsr-82.)
But I only start implementing if there is demand for it. Please state also if you need a symbian or mobile java application.
