You might be interested in this SSH Update layer:

WordPress has built-in support for the PHP SSH extension, but it requires it
to becompiled manually, that library & plugin will allow it to be done in
pure PHP.
I havn't tested the plugin, and have a few suggestions for the code as it
currently is, but it's a option for you
