Creating Rich Client Linux Apps with XPSL

Tonight I've coined the term XPSL to stand for making a rich client application on Linux using Mozilla XUL, PHP, SQLite, and Lighthttpd. The way it works is that the one XUL file is loaded as a chrome for Firefox. This in turn calls Lighthttpd which then calls PHP. The PHP then interacts with a SQLite database. The only catch is that I want to work on compiling PHP4 with Lighthttpd together in the same directory and not have this PHP4 interfere with any files in /etc, /var, or /usr. Instead, you run it from the single directory in standalone, unthreaded mode because this is not a web app we're talking here, but a rich client standalone app. If you have info on how to compile PHP4 and Lighthttpd in this way, drop me a blog line at http://supermikenews.blogspot.com . Thanks.
