I would love to see this as well, I thought there was something needed with the boot loader being completely unlocked though so that Ubuntu can rewrite the partitions as it's needed.
If that's still correct, we're kind of S.O.L. since at most all we have is Loki, which, while it allows us to install recovery and ROMs, is not a true bootloader unlock, and from what I hear, it's starting to sound like a true unlock may be damn near impossible.
I'm still holding out hope though, Ubuntu Touch would be awesome on here.
