Wikipedia support

Hello,
I am looking for a plugin that can AUTOMATICALLY pull content and populate my term pages with wikipedia content and/or show wikipedia content on the tooltip popup.
Questions:
1. Wikipedia support is only available in the ecommerce edition, correct?
2. How or when does the plugin pull content from wikipedia? I mean does it in real time every time the page is loaded (which would affect speed of page load) or does it populate its database with wikipedia content when the term is added to the plugin? In latter case, how often does it refresh content by pulling latest version from wikipedia?
Thank you for your attention.
