There's OSM editors that will source imagery over SMB? I've never looked
into it, but I'd be surprised.

Thinking about this very quickly, my points would be:

1: RAID: I'd want some disk redundancy as the device is likely to be used
in tough environments that are far from good sources of replacement disks,
or replacement imagery.
2: Software: As already mentioned, you're going to need some software to
serve the tiles. WMS? You'd want a device that was easy to get running with
third party software. Performance may also be an issue, depending on how
many people you were catering for.

I hope someone will come along with an example of what they've managed to
do before. If not it should be a fun exercise :)

Cheers, Joseph
