[OpenLayers-Dev] Further to client side grouping...

[Phil Scadden]

I would also point out that there can be a difference between grouping 
for user-presentation (eg you may have a group called "infrastructure" 
which has data from several different public servers) and grouping that 
might be logical from optimisation point of view (all layers on same 
service). From a performance point of view it would been better if 
optimization of requests to server was happening in the background. To 
that end, I would like to see a "logical WMS layer" (what creates with 
.Layer object) and a hidden "physical WMS layer" which is grouped by 
server. ie When a logical layer is created (or its visibility changed), 
then the physical layer list is searched for same server url. If 
present, than add the layer; if not create it.

Do you think this would work?
