BTW, your code works very well on my setup. I'm using an ATMega1284P with the Maniacbug Arduino mod. My HW is clocked at 18.432mhz (EXACT multiple of common baud rates, and I had a rock on that frequency). I removed all of the transmit code, and all the receive code for everything other than the NEC protocol (since that's what I'm using and I don't need the transmit functions). I'm using timer3 on the atmega1284 (since that time uses the SPI pins, and I don't need to generate PWM).
As I wrote before my only concern is the background overhead when not receiving IR, so I might look into shutting down the timer until an opening wavefront is received, then shut it down again a few seconds after the last IR signal is found. My selected receive pin is an interrupt line.
