ZenCast Organiser?

In my continued quest for the perfect podcast player, I had a look at Creative’s offerings. They seem to offer a piece of software called ZenCast Organiser that offers podcast management and synchronisation.

ZENcast Organizer seamlessly integrates ZENcast media files with Creative portable media players and/or your computer. Some portable media players may only support ZENcast audio files.

Is anybody using that and can point me to a review? I’d like to know how good it is in relation to iPod/iTunes, i.e. does it delete already listened to podcasts from the mobile device?
