Yep, that's exactly what I had in mind.

Eric suggested to use the protocol.commit() function, but it has the 
same problem ( no fid on new added features ), so I'll have to implement 
one.  I'm still trying to figure how to just add function on commit(), 
there's already something for that but I'm missing something because 
when I set one, it replaces what is usually does instead of adding one :

        olWFSRoads = new OpenLayers.Layer.Vector("Roads FS GeoJSON", {
            scales: oMap.getScales(8,10),
            styleMap: oStyleMap,
            strategies: [new OpenLayers.Strategy.BBOX()/*, oSaveStrategy*/],
            protocol: new OpenLayers.Protocol.HTTP({
                url: szFSURL+"/bdga_route_l_arc?format=GeoJSON",
                format: new OpenLayers.Format.GeoJSON(),
                create: function(){alert("foo")}  //<-- this gets 
triggered, but no POST is created...
            })
        });

I'll continue to look deeper and try to understand this.

Thanks,
