Hi,

I think such a device would be awesome! If combined with the icicles
app, it could make using darknet very convenient.

This could also serve as darknet peer to a node which runs on another
computer.

Since this is a problem we’ve seen in the past, and since this will be
an always-on device (many¹ USB hard drives have problems with sustained
load, and many¹ SD cards aren’t built for constaint rewriting), I’d
suggest using 512 MiB of pure ram-storage. Then we could guarantee that
freenet would not create strain on the device.

¹: It doesn’t matter that there are ones which work well if we cannot
   guarantee that users will have one which works well.

My base nodes without WoT work well with roughly 500MiB of memory and
just about 10% load (on a 2x800MHz system).

Best wishes,
