Hmm.. while it's similar to JTAG. One of the differences is though that you need to enable DW mode first, which requires SPI if the fuse isn't set. So you use the limited SPI interface of the MK-II to enable the DW fuse then use DW to download code, then disable the DW fuse. Of course though you can also just enable the DW fuse once, then disable it later. The interface is a bit trickier because if you enable the DW fuse you cannot use SPI for programming, so you need to remember to disable it! Anyway the DW interface actually isn't used in AVRStudio to download code. However it is capable of it, but it is more of a debug interface. However only using one line to download code can be useful in development so you don't have any load on the SPI lines.
