Yep, I do use optware and it's worked fine for standalone apps like noip duc and vsftpd.
For php I want to integrate with the existing lighttpd server. I believe that the tutorial describes the whole setup including (re) configuring lighttpd. As a complete Noob I'd like to be led by the hand on this rather than break the existing functionality.
I was also hoping that the tutorial would have a walk through of re-compiling lighttpd. I would like to have regex support (for virtual server host names).
