Green Building Q&A: Do retrofit "air tight" electrical boxes exist?

I read with great interest this article back in Feb http://www.greenbuildingadvisor.com/blogs/dept/building-science/air-leak... However, what continues to surprise me why they have not come up with a airtight retrofit electrical box. It would seem this market is where they should concentrate? New construction and using this type of box seems like a no brainier. Where help is needed in the old drafty houses! Anyways........... does anyone know of a manufacture that makes a airtight/vapor retrofit box? Could you simply cut the flanges off a new construction airtight box and then caulk the seam tight to the drywall/plaster? That seems like the most efficient work around instead of trying to caulk all the penerations in a normal box This would be an example of where I would cut the flanges off and then caulk the seam bewteen drywall and the box http://www.homedepot.com/p/Carlo...
