If you like to play around with code then you might be interested in taking a look CyanogenMod 11s kernel for the OnePlus One.
The kernel which CM have released won’t allow you to give you a full 11S ROM however it still has enough there for talented developers to have a good crack at building something out of it. Anyone can download the kernel from Github right now from the source link below, If you do have a poke around let us know if you find anything interesting.
I wonder if this can be used to build a CM11 ROM for the other Find 7 variants?
