 I get that you can request the layer in whatever projection (SRS/EPSG) you specify in wmsLayer.js. The problem is (unless I'm missing something), requesting an extent/bbox in not-lat/lon (which happens when you're using a projected projection) returns an error or nothing from the server (they expect lat/lon?). Assuming that, I was presuming that we would just have to convert the bbox from projected to lat/lon to get a valid image back?

automatically pick up the map projection.  This probably isn't that  
tricky to add, as long as the output projection at the MAP level is  
set and is an epsg code.  This would be a change in init.php ... I'm  
not likely to attempt this soon, so if you give it a shot, lemme know  
if it works and I can add to cvs :)
