Well this is one of the coolest things I've seen today. I appreciate the amount of work you did to document the package.
My vote is conditional, as the package is not packaged properly. Files are not following the file name conventions and no package.xml exists. If you have questions about making this into a PEAR package, #pear or pear-dev@ can direct you.
The ZIP file you provided is also corrupt -- I can only view and extract the firephp.php file.
Additionally, this package depends on a non-PEAR package and I'm not sure what PEAR's stance is on that.
