coord_proj with recentered map

[natemiller]

Is there a means or can there be a means of using coord_proj on a map that has been recentered (using maptools, nowrapRecenter)? I often need maps where paths cross the dateline, but where the ability to use coord_proj to set map limits would be very useful. Does coord_proj only work beyond Atlantic-centered maps or shapefiles?

I am wondering the same thing! Couldn't cood_proj have an "orientation" argument, as exists in ggplot2::coord_map()?
