Not trying to embarrass Chewitt here at all, but there is a new Linos launched in April that has Jarvis 16.1, and was published in the OS X sub forum on the Kodi forum (and yes, Chewitt commented there on it also! He said deja vu, hahaha!).
Linos is based on Ubuntu 12.10, stripped way down. (and no PVR built in). I just tested it last night, works well.
I am not going to write too much about that, as this is still the LE forum for ATV1, and I will leave it at that. If you are interested, find it in the Kodi subforum there.
Thanks Chewitt for all the hard work anyway on LE. Much appreciated!
