How would you go about controlling multiple transmitters?  Multiple 
serial ports each with an instance of LIRC?

I just bought a second Dish receiver and am currently working on the 
improved transmitter ( http://www.lirc.org/improved_transmitter.html ).  
I can't figure out if the red (and possibly IR) LED is supposed to 
always glow and flash brighter when sending a signal or if I have some 
current leakage somewhere.

I'll admit I never thought of the opaque tape for preventing 
interference, but I didn't trust more than one simple transmitter on a 
single serial port, anyway.  Regardless, my motherboard only has one 
serial port--and doesn't even have headers for a second, and the thought 
of spending $30+ for a USB-serial connector that might work or $30 and a 
PCI slot for an I/O card was not at all appealing.
