Wireless/bluetooth shuttle + transport controller?

[merges]

I'm looking for a jog wheel / shuttle and transport (i.e. record, play/stop, next/prev locator) controller. It could be similar to the Contour Shuttle Xpress. But I need it to be wireless/bluetooth, so I can easily move it around the studio. It seems like such an obvious piece of kit but I haven't been able to find something like it. Any pointers?
