This sounds so great! Personally I would go for two boxes, since I may want to have the router running 24/7 but not the file-server/backup-server. I find all-in-one solutions also to be more and more a pain to administer. Maybe even three, since a media-client is also a need, though I backed the OUYA, so I will see. What about Linux? Is this simple? Possible at all?
It's great to see such a product targeting this at the home market.
What about video? I am not set up, yet, but I plan to use some networked DVB-receivers (you may know them, all they do is grab the signal from the antenna and offer them on some port for the network to get). I don't know the technical background, but I think this is not as simple as supporting the four major condecs in two major cotainer formats, like most Chinese boxes do. Also, they have performance problems with real HD, meaning bitrates >20Mb/s. I guess this is also one of the problems, the XBMC guys are facing for their Allwinner A10 port.
Am I right in the assumption, that, as a consumer, I could not simply order or even use your product, since it would still require some hardware work to be done, mainly the I/O and require orders >1 piece?
