You still have the overhead of two nc instances copying data and context switching. The same is also the problem with the "ssh -c none" approach. My original proposal would setup a direct socket connection from tar to dd. I think I can package the proposed sh changes as a separate command, following Luigi's suggestion. The syntax will not include a pipe symbol and layout, but the performance benefits will still be there. It will also be a lot more portable and also usable within any shell. Many thanks to all for your feedback.
