That will work for a 'Layer.WMS' or a 'Layer.MapServer' layer, but for  
your vector layer you'll have to cobble-up something on your own...

I recommend splitting at the 180 boundary, as you mention, and draw  
multiple representations of each line segment (shifted 0, -360, +360  
degrees longitude) to make sure that as the user is panning to the  
left or right the track doesn't disappear.
