I discovered the AVR ISP Shield - PTH Kit today, and I really like the idea.
I suggest SparkFun make a version of the AVR ISP Shield that has a socket for TQFP and/or QFN instead of the DIP socket.
More Atmel microntrollers are available by far that use a SMD package than there are that offer DIP packages, so offering a SMD version if the AVR ISP shield would make sense.
Thanks,
Max
