[OpenLayers-Users] Is there an example of using layers with differing source projections.. ie using Proj4?

[Lance Dyas]

The example usage I am thinking of is where I have a WFS layer of one 
projection and mayhaps a WMS of another.. WFS 1.0 seem inclined to 
answer in whatever projection they have... I think it is in 1.1 that you 
are better able to specify you want the layer in a specific 
projection..and actually get it in that projection.
