From the responses I'm getting in the "[OpenLayers-Users] Switching Layers Assigned to a SelectFeature Control" thread and some Googling it appears that handling multiple vector layers simultaneously in OpenLayers is not well supported. In fact, it basically won't work. Only one layer of features can be selectable at a time.
What I'm trying is to create only one SelectFeature control, but then allow the user to pick which layer they want to be "active". After they choose, I destroy the current SelectFeature control and replace it with a new SelectFeature control that uses the new layer. It's not elegant, but it seems to work.
