Bad stuff belongs on the list as much as good stuff.

As for PHP warnings:  perhaps the PHP client maintainer can submit a fix,
or somebody who knows PHP... I'm rusty.

About the Storable error:  you can't mix and match use of Perl and PHP
when it comes to frozen structures.  Perl's storable isn't compatible with
PHP's.  If this is a requirement for your app, freeze/thaw on both sides
with YAML or XML, which work on both.  We used Storable for speed and
memory efficiency.

No C library?  Make one and we'll maintain it.  The protocol isn't
changing, and is now documented in CVS under doc/.

Other than the PHP warnings and perl/php binary structure mismatch, did
you find any real bugs?
