I definitely have a need for this, but I can't stomach same-network requirement.
Maybe they need self-hostable coordination server so that devices can connect to each other through it.
For now it's still 'send to telegram saved messages' for me.

What a long way to spell VPN :-) (been using it for a decade or so through wireguard)
Not sure if it's the best solution, but there's no reason to take over your entire network.
Even with my old OpenVPN setup I had a config where only my local 10.2.0.0/16 got routed over the VPN, everything else went straight to the outside world. Set up IPv6 ULA and you don't need to worry about IP addressing conflicts.
The Android app let me add a peer by IP address. Once I opened traffic on the right port, it crossed a network boundary just fine.
My case was an adjacent network, but I don't see any reason why it wouldn't work across more hops.
