ssh-copy-id for automated pubkey append
// it's simple to add one key but this helps when i'm on a machine w/ multiple authorized hosts
// use like `ssh-copy-id ww1.example.com` -- make sure you have `ssh-agent` running and have added keys w/ `ssh-add` (use `ssh-add -L` to check)
// got this from the OpenSSH in Ubuntu, don't have it on mac afaik?
