Control All av with one uirt? Question before purchase

I have all of my a/v equipment (+htpc) in a standard shelved TV stand with a glass door.
I assume I will have a problem using one usb-uirt device to control all of the equipement through girder+htpc since it sends ir in the same direction that it receives a signal.
Am I assuming correctly? If so what are my options, an ir emiter attached to the back of the irt?
Or is there some way to position the uirt to receive signals from my remote (from couch facing tv stand) and send to equipment?
This would seem like a common issue...
Thanks much
