Would this be solvable by integrating support for Keybase or something similar? Come to think of it, someone else complained about the amount of local storage this uses, and Keybase includes some gigs of free cloud storage as well...
In theory, yes. I asked this exact question on the scuttleverse a while back and the answer was basically "that might work." This was back when I was still using my old iMac, which is still the only device my scuttler identity exists on. Heh.
is it gone? Otherwise you just have to recover the .ssb/secret from your $HOME.
It's not gone. I'll transfer my ~/.ssb stuff over one of these days.
