Hi Robert, Basically, it is not possible, as the client doesn't know about features, since they are visually part of the WMS layer.
Anyway, the WMSGetFeatures request (OpenLayers.Control.WMSGetFeature) would catch user clicks and ask the WMS server to send back any features on that location. If you want the mouse cursor to change upon hovering, 2 solutions: 1. trigger WMSGetFeature after every mouse move (for ex, after the mouse has stopped moving for 500ms). For that, the WMS server must be optimized, as it will have to handle more frequent requests. There is still a delay (reactivity vs. server load), but you are not limited in the number of vectors as a vector layer would. 2. take the approach of Google: business places are clickable, although still on an image layer. I don't know how they do it (JS computation on every mouse move? or use of image <area>?)
