NAT makes this kind of stuff impractical now a days b/c you can't really host anything from your own machine (well you can set up port forwarding if you can access the router...)

The easiest modern solution would probably be git pulling from an Onion address (running git daemon so it's read only). Then, when your machine is on, people that want updates would just

    git pull git://abcdef1234567890.onion/fingerfood.git

Though tbh.. the single-file setup of finger is cuter than a whole repo directory
