I would LOVE to do this... post some instructions on how to make it?
Here is the location for viewing the MythLED box we made.

It uses a standard serial interface to communicate with the monitoring
software. The software queries the mythbackend to get the status of
the tuners, free drive space, guide data, and voicemail. The MythLED
box can be located anywhere. We are running this one at work and it is
showing the status of David's Mythbackend at home. The prototype we
made is capable of showing the status of 5 tuners. It will
automatically determine how many are configured and show GREEN for
Idle, RED for Recording, and Off for No Tuner. The System led will
flash Red if there is something that needs attention like the hard
drive space is low or the guide data is out of date. The Message led
will flash Blue if there is a voicemail waiting. There are two Antenna
leds that will turn Yellow to indicate which antenna is selected. We
did this because we needed to switch between two antennas for HDTV
programming. If the mythled software looses communications with the
backend it will flash all the leds and also sound a piezo buzzer.
I will clean up the schematics and get something posted. If enough
people want it we can have a few boards made. We had some extra circuits
that we will probably remove. I added a IR transmitter but have not
implemented it yet (probably won't because there are already so many
available). It uses a simple bit shifter and two lines from the serial
port to set the led's. We have bi-directional (bi-color) leds for the
tuners so they can be Green/Idle, Red/Recording and Off/Not Available.
