There could be something interesting coming up, in the context of OXNAS based devices.
I just found a review of Shuttle's KD20 NAS. This is a recent NAS System, that is based on the same OXNAS 820 CPU that the Pogoplug V3 devices use.
Maybe the sources that Shuttle will have to provide, can contribute some interesting new patches or something like that.
Unfortunately I couldn't find any files from Shuttle, while doing a real quick search this morning. Anyway, they will have to provide something, or they could have a big problem.
Update:
Just sent a short mail to Shuttle support concerning the lack of published sources. I'm very interested in seeing how they will react. I have a hunch that they thought they could get away without publishing the files.
Update2:
It seems that Shuttle really thinks they don't need to publish any source code. At least they totally ignored my question concerning it. Quite questionable if you ask me.
