I'm realising now that I answered a bit too quickly: you would need to 
perform some tricks to do a GetFeature request, including transforming 
the click coordinates to lon/lat values etc. As a punishment for myself 
I created an example [1] based on the standard getfeatureinfo.html 
example. It's not perfect, but it works :-)

A few things to look out for:
- use 'ows' in your url instead of 'wms' or 'wfs'. OWS captures both, 
you just need to specify the service explicitly
- make sure that if your geoserver runs on another port or another 
machine that you have a proxy script
- look at the 'propertyName' parameter. That one tells the WFS service 
what attributes to return.

Good luck!
