HTML_Template_Flexy and DB_DataObject with Paging (and lack of flexy:while)

I'm interested to see if anyone has come up with a nice paging system using Flexy and DB_DataObject, ideally the formatting of the pager and the number of results per page should be done in the template. One huge issue I've come across with limiting DB_DO objects from the template would be running a while loop over it, because flexy doesn't offer a while loop feature. I would be very interested to hear how people have intergrated these classes. I could do the while loop in the Page class pushing data into an array, and then the template can do a foreach over the array, but this is inefficient and wouldn't allow for results-per-page limiting on the template. Ideas/Suggestsions very welcome! Kind Regards, Ian
