Alas, time has caught up to me. I will not be able to get the touch trackball controls working in time for the submission deadline. Instead, I need to use this remaining time to package up my work and create a more thorough write-up that details what I have done and what is left to be done.
I'm still excited, though, since I got all of the minimum requirements of my proposal done and have gotten a good start on a few extras. I will be working beyond the end of GSoC to get iOS support to a ready state.
See you soon!
