I'd like that (and contribute to a bounty) too.

Zeus connected to Start9 using Lightning Node Connect works ok-ish, but is still kinda slow and crashes a lot.

I've no idea how to install Tailscale on start9 to even try if it would work any better,

so some easy solution like direct integration in apps and a Start9 package (at least while there's no clearnet-support) would be much appreciated.
