I am very happy with ireal b but it would be fantastic if there was a way to remotely step onto the next song (which could be another song or the next page of a song). Not too bothered how it's connected - could be Bluetooth, WiFi or usb. Be great if it was a small Bluetooth switch that could either be stuck onto an instrument with a suction pad or just a footswitch. Whatever is cheapest and easiest to produce - maybe an app for a phone that can control a tablet pc could be an option. If it was the phone option I can imagine 2 big icons - one to step forward and one back. Ideally android because there are plenty of cheap 2nd user ones available.
