I wrote a shell script to download a copy of my.webfaction.com using wget.
I've been cross referencing my.webfaction as I migrate all my content over, and I wanted to save a local copy of it, because who knows when they'll turn off access.
The script will prompt for login credentials, then login on your behalf, and save a folder full of files that contains a fully browsable, local copy of the site with your account data. Because my.webfaction uses ajax to populate parts of the interface dynamically, it's not a full fidelity copy, but it's close.
