From the first post:
As a follow on from my previous entry about OpenID in the Zend Framework, I've been in brief contact with Dmitry Stogov across a scattering of emails. Dmitry posted his OpenID proposal for the framework over at the Proposals Wiki earlier in the week. [...] It's actually very hard to comment constructively rather than simply handing over my code which probably says a lot more all by itself. [...] Anyway, I've agreed to port my OpenID library to PEAR as a PHP5 package. I checked with the mailing list, and the approach I've taken in splitting the library across a number of freestanding components hasn't seen any objections. On the flipside, it does help by providing upgrades to existing PEAR Encryption packages which are not yet migrated to PHP5 versions.
And from post number two:
Over the weekend, I managed to grab a few hours to dig around my OpenID library with the ultimate development tools: patience and experimentation. [...] What I've refactored towards is a splitting of the OpenID process based on three categories: Request, Redirect, Response.
