Mike, please excuse my ignorance but my DIY electronics knowledge is limited at best. Does Enrique's method allow you to transmit unique IR codes to each box? So there would be 2 light emitters? If so I'll definitely give this a try.

To use multiple IR transmitters, you'd have to a) connect each to its own serial port (do you really have enough serial ports for this approach?) and install multiple copies of LIRC such that they don't interfere with each other (i.e. as shown at http://losdos.dyndns.org:8080/public/mythtv-info/MythTV_DISH_IR_LED_TX_via_M odified_LIRC.html ) b) rewrite LIRC's serial driver to support multiple transmitters using the different pins of the serial port. This would also require rewriting most of LIRC to support multiple devices (transmitters/receivers). To use the improved serial transmitter, you'd have to a) throw together a bunch of electronics components b) get a friend to throw together a bunch of electronics components I highly recommend the improved transmitter.
