Thanks! I looked all over for something simple like this. I couldn't get RESTful routes working with yours so I kept digging.

There is a helper in ActionView::Helpers::UrlHelper called current_page?(options) [http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html]

def sectionlink(name,options = {}, htmloptions = nil) if currentpage?(options)
linkto(name, options, :class => 'on') else link_to(name,options) end end

This allows for RESTful links as well:
