After building a lot of multi-touch prototypes with normal IR leds, one of my co researchers, Peter Bomark, did some prototyping with Surface mounted leds. Eventhough this approach requires more knowledge of electronics, we prefer the use of this method above normal IR leds, because of the efficient spacing and the clear and professional look of it. Mounting them is the biggest gain and wiring is less hassle. The leds we used are the SFH421.
