Are you familiar with stdin/stdout/stderr on Unix and how they interact? What ssh does that I find so powerful is ensure that what you put into stdout on one side of a pipe flows out of stdin on the process that ssh starts on the remote host. Of course, ssh also gives you the output of the remote process, so you can put an ssh command in the middle of a pipeline. My day to day life no longer involves interacting with lots of remote Unix systems, but when it did, it was really, really useful.
