Seems awesome. Can you please tell us how to use gzip or lz4 to do the imaging?

If you search for “dd gzip” or “dd lz4” you can find several ways to do this. In general, interpose a gzip compression command between the sending dd and netcat, and a corresponding decompression command between the receiving netcat and dd.
