I've played around with a number of Monoprice IR units. The 108060 is the same unit that comes with their HDMI over CAT6 wallplate, and it's only single band IR (meaning it won't work with all remotes / devices).
The IR receiver that comes with their IR Repeater (9895) seems to work with everything that I've plugged it into. I don't have the Sony projector (yet - theater is still under construction, so it'll be a few more weeks), but I'd be willing to bet if you pulled the IR Receiver out of the box that comes with the 9895 unit, it would work, and the 108060 won't because the band of IR for the projector isn't covered in the 108060.
Whenever I use one of their HDMI over Cat5/Cat6 wall plates, I throw away the IR receiver (same as the 108060 unit), and use one from the 9895 instead...YMMV of course with the projector, but if I were to bet...I'd say it would work there as well.
