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 or

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