[OpenLayers-Dev] Some thoughts on client-side grouping.

[Phil Scadden]

I read http://ol-performance.appspot.com with a lot of interest, 
especially the client side grouping. However, it occurs to me that when 
you open a "Layer" object in OL, the object has both client side config 
options (eg displayinLayerSwitcher) and server side (URL). You cant 
exactly group client side if the layers have different client-side 
config options. Would it be possible to have OL do the grouping behind 
the scenes? Ie if layers have same server characteristics, then group 
them so that the tile request to the server has all the appropriate layers?
