Brad, thanks for your thoughts.

We used to have an IE-only SVG map. It was slow loading but a lot of useful
data was in the browser so we could do instant tooltips on mouseover. We
have since moved to a cross-browser tiles-based system (thanks to
OpenLayers) and so we're trying to implement as much of the old
functionality.

The idea is to use a WMS layer exclusively when zoomed out, switching on the
supplementary vector layer at small scales. I'm conscious of how heavy the
WFS request can be.

Cool, I'll try it. I've since seen an example where two SelectFeature
objects are applied to one layer, so I'll look at that too.
