Nope, re: SSH. Tailscale should already work on a Sprite. Everything we do at Fly.io is connected by WireGuard, so it's just a question of whether we want to expose that to users.
Tailscale definitely had issues for me, unless I used user-mode networking and even then it was iffy. I should add that it also auto-signed me up for a trial of Fly.io itself, which is useless to me now but might've come in handy later.
