ardweeny programmed via a duemilionove?

hi, I just ordered an ardweeny for an embedded project:] but im too cheep to buy the ftdi cable, reason is i have a hunch that the ardweeny could be programmed via the use of a duemilionove ? anyone else tried this before?

you could use RS232 like http://arduino.cc/en/Main/ArduinoBoardSerialSingleSided3 or http://imagearts.ryerson.ca/sdaniels/physcomp/tutorials/arduino_serial/ard_serial.html

my objective is to pull it off without having to buy the stupid ftdi cable or some serial port adapter
