Anita would work well too, it has all the visemes and animations needed, and a lower price tag too.
The Zabaware engine will not replace Haptek but will be offered as an alternative for as long as Haptek allows. The Haptek engine will always be available to be installed as part of the expansion set that is available now. My goal is to make a Zabaware version of the Hal and Zaba characters and remove Haptek from the default installation of Hal, but the character expansion pack will be able to bring Haptek support back in.
I'm still waiting to hear back from the authors of the characters about my questions on the licensing terms. My goal with the Zabaware engine is to make everything user customizable and editable. But if the authors of these characters require it, I may have to lock it down just for these characters. If this happens, I promise that future characters made will be customizable.
Clothes in Zabaware engine can be either as a texture or a prop. It looks like the clothes on the linked characters can be setup as props. Props can have indepedant motion from the main character. Characters in the character engine are configured using an XML file which tell it what models to load, what textures, and what animations. This is user editable and you can usually swap out textures by making new JPEGS and XML definitions.
