Sounds good.  The USB IR receiver will be used to control myth.  For the 
Directv serial cables just use the ones described at 
http://www.dtvcontrol.com and the script from 
http://bach.as.arizona.edu/~johng/rca_control.txt .  There is also a C 
program which reportedly has better performance, but the above script is 
just as fast for me and works flawlessly every time.

You use the remote with LIRC to control Myth and myth controls the 
Directv boxes with the external channel changer command mentioned above.

Add-on serial cards are supported and not a problem.  Also, you can use 
USB to serial adapters.  I picked up a couple on eBay for $5 each and 
use them to control my RCA DRD435's.
