Free extensions for Joomla!

Hello. I installed your plug-in. It’s excellent. I want use it in Virtuemart to add product ratings! I don’t use standard Virtuemart rating plug-in because it need person registration. In you plug-in every person could live it rating without registration. That’s why I heave a question: it’s possible to integrate your plug-in in Virtuemart??
Thank you for all answers.
PS. Sorry for my English.
