If you're among those who enjoy digging around the inner workings of things then you'll be pleased to know the Cyanogen Inc. has updated the CyanogenMod Github account with the kernel source files for the OnePlus One.

You won't be able to build all the goodies found in the 11S ROM but if you've got some skill in the matters you should be able to get an AOSP or CyanogenMod build up and running. If you're not skilled in such things well, back to hoping you get an invite if you haven't already.
