A kickstarter campaign just popped up today that seems very ambitious and useful at the same time. Mainly, this will be useful for Lego Technic MOCers who want better usage of remote controlling their PF-powered creations.
Basically, it is a new receiver that has four outputs. The receiver can be connected to a smartphone via BlueTooth and thus has a far better range and is not affected by sunlight. Also, there is no restriction for 4 channels in a tight area anymore.
The creators also made a video that shows how this new receiver works:
