I just tried the first batch as a torrent and it worked fine for me. Note that IA torrents are hosted as web seeds, so if your client doesn't support that, you won't have any seeds.

Also note that I don't think the hosted versions can be imported back into the Lytro Desktop software, if that's what you were hoping for; they're just stacks of JPEGs, JSON metadata, and the depth map data.

Rehosting an individual embed should be pretty straightforward, just replacing the CDN URLs with relative or absolute ones to wherever it's been rehosted (or to Wayback Machine URLs). I'll be writing up some details at some point, but don't wait on me.

Rehosting an entire user's "pictures.lytro.com" gallery was trickier than that, I don't think I was able to get it working locally.

Good luck.
