I think that their proxy technology is just a wms wrapper for tiles. So 
clients can pose wms style queries, and the server assembles the 
relevant tiles into one image, and sends that image back to the client 
as a wms response. Of course, this only works when the client requests 
only a small set of possible scales, covered by the tiles. I guess the 
only advantage is to enable wms only clients to consume TMS tilesets.
