Custom USB-UIRTs?

I was wondering, if it would be possible to get a custom USB-UIRT built, at an added cost of course. What i'd like to have is all the emitters be external (with 3 seperate 1/8" jacks, or maybe an RJ45 jack, and the receiver be external as well (in it's own seperate little box, maybe with a 1/8" or RJ45 jack?).
The reason for this is that in order to use all 3 zones to blast devices, you'd literally need to tape the front of the UIRT to your STB, and then you'd lose the receiver. The reason I'd like an external receiver, is because my HTPC is setup in my equipment rack and I need about 65' of cable to extend to my living room. I have currently got the IR receiver from my PVR-150 card extended to the HTPC from the living room over Cat5, but if I end up going with another HD-PVR I wont' need the SD card anymore.
These hardware changes shouldn't need any major modifications to the current USB-UIRT, and no changes to the software either.
Thanks
