Show HN: Altersend – File sharing without cloud

Looks neat!

I don't mean to be dumb, but it's hard to find docs on how Hyperdrive works. The Hyperdrive github just links to https://docs.pears.com/building-blocks/hyperdrive/, which links back to the github, and the docs seem mainly API docs.

Under the hood, what does Hyperdrive actually do? How does this navigate NAT, etc?

Can you explain how it passes through firewall and lands on a somewhat listening socket on the remote, without being abused meanwhile ?

476.7MB Windows binary...are we really doing this?

Great utility! Wonder if this can pause and resume the transfer as well? Haven't tried this yet. Just read through the repo.

Sounds promising!
