I found this on Github:
Also, Walid showed his Moto G to boot into Plasma mobile here.
Because of that i was under the impression that his Ubuntu Touch port also was based on Halium although I very well can be mistaken.
You say that there are certain issues with Halium to work reliably. I'd very much like to know more, is there a link or something, the issues page on github doesn't show much details.
Are there actually any real devices which are supported fully by halium?
Also, which distribution is most likely to work with a halium device?
