Q1: is there a way to download the resulting screencast so that it can be viewed off the network?

Q2: is there a way to do this without having to upload anything? e.g. pipe to a file locally?

try script(1) and scriptreplay(1)

Or ttyrec(1) and ttyplay(1)

This unfortunately doesn't support the use case of simply wanting to personally back up the screencasts sent to showterm.io.
