Network Your Shell Scripts with Netpipes by Robert Bernier -- Shell scripting and automation are an administrator's most powerful tools. Unfortunately, many processes require transferring data back and forth between machines. Instead of tunneling yet another app over HTTP or writing yet another ad-hoc protocol, why not use netpipes? Robert Bernier explains this set of utilities that provide network-aware pipes to shell programmers.
This looks interesting. I wonder how it would fair against ssh, though. My opinion based on a quick browsing of the article suggests to me that Netpipes covers a different kind of situations from what ssh can do. With luck I will find a few minutes to really look into this and maybe write an article on how it compares with ssh's remote script execution capabilities.
