Speaking of which @Jwintern, did you ever get the node running on that Orange?
Nah, but there are builds for raspberry pi so I think it should certainly be possible to keep up to date with a little arm chip at this point.
I have a xmr pi node running now. Used this guide -
http://pinode.co.uk/Did it on an sd card which apparently have about a year life span with the constant read/write. Wish I would have known that from the start.
I want to say it took a little over a week to sync but it stays up to date just fine. There's a few scenarios where I may use it as a remote node but was really just a tinker project.
