Dude.... I get laughed at for the things I do with templates (html page with 20k input elements) until people realize what I am doing with them (a bulk payment interface for paying 5000 invoices in a compact workflow). I have found that any complete templating system has sufficient flexibility and extensibility to do what you want. Though I use Perl's Template Toolkit.
