These two are the NUCs which we had at camp -- I'll bring them to congress too, so they'll finally get some combat experience :)

namaka runs dev040 and is already bootstrapped, while hiiaka will run master. I'm referencing them by their cjdns IP because they don't have a fixed IP address on their own. If we lose connectivity, we'll have to hook up a cable and do link-local SSH.

About the names:

Namaka is the smaller, inner moon of the dwarf planet Haumea. It is named after Nāmaka, the goddess of the sea in Hawaiian mythology and one of the daughters of Haumea.

Hiʻiaka is the larger, outer moon of the dwarf planet Haumea. [...] It is named after one of the daughters of Haumea, Hiʻiaka, the patron goddess of the Big Island of Hawaii, though at first it had gone by the nickname "Rudolph" by its discovery team.
