[OpenLayers-Users] Hover control sample (share)

[Alexandre Dube]

Yeah, I saw your example a couple of days ago.  It's a great tool.  As 
vector features are longer to draw than samples images generated by WMS 
requests I find this quite useful.

The slow rendering of vector features has been one of my worries.  A 
common practice is to normalize the geometry for a given scale or have 
different data per scale on the server side.  With that in mind, I 
wanted my vector layer to load features from different data source.  See 
the example :

This combine the above idea ( multiple data sources ) with the Hover 
control.  The result is quite fast.  What do you think ?
