DataObject: quick opinion poll

I was wondering how everyone here does their result paging when using DataObject. I generally create a client class that has member vars (current_page, results_per_page) for paging and control everything with post vars(first, back, next, last). This has the benefit of not having to deal with reading and writing to the url string, making it easier to integreate into other pages. The penalty is you can't send a link with the page info. How do you do it?
