Sounds okay to me.

If the HTML generation is what you need it for, just add something  
like a getView() method to the objects that returns the appropriate  
Horde_View object; the html will be encapsulated in the templates for  
the view.

Actually don't really use Horde_View since that's a Horde 4/PHP 5  
thing, but the concept applies.
