[Zope] ZPT instead of DTML Methods

The http://www.zope.org/Members/johanc/IEMethod/IEMethod product is baseclassed on DTML Methods. Can this not be changed to ZPT instead? Because then one would be able to insert business logic without fearing that Microsoft messes with you. I've noticed that DTML makes IEMethods pretty irreversable. Can this be done easily d'you think? I'll maybe give it a go. Peter
