It would be really useful to have a shield(s) that you could solder a small surface-mount part to. Definitely for advanced users, since reflow would be difficult with the plastic connector on the bottom.
I envision a surface mount footprint on the top, with through-hole pins corresponding to the pins on the chip, then an outer ring of pins to breakout the 'duino. high density headers could then be soldered in to jumper the device's pins to the 'duino pins.
