First of all, awesome plugin.
Basically, I have a local business directory and think your comments and ratings are the perfect replacement for the default comments section in my theme. The only thing I am wondering, since the review is not about my site or business, is it possible to have the hcard auto populated from meta data fields. If so, where and with what would I populate the fields.
I have custom data, Name, Address, City, State, Zip, Phone, url
Not really sure where to go from here. I attempted a couple things on my own, but the site either crapped out or just showed the php code.
