Many people are combining PhP and MovableType in interesting ways. However, there is a significant limitation. PhP has no direct access to the beautiful Perl API of MovableType.
Enter Mason. Perl based dynamic pages with much the same spirit of PhP. Yet since Mason is written in Perl, it can use the MT Perl modules. Meaning dynamically generated pages have access to the same store as MovableTypes static generation process. Cake and eat it too.
