I just wrapped up a little step-by-step on turning an FTDI cable into a Parallax Propeller programmer. The instructions can be applied to any FTDI breakout board, might be handy if you have a Propeller but no propplug kicking around.
From Hackszine… Robert Quattlebaum undertook the task of creating the new version and teamed up with ladyada to help bring the new kits to the hacker masses. It’s built around an 80MHz 32KB Propeller chip, supports NTSC and PAL, and comes prepackaged with a bootloader that allows you to upload new firmware over ethernet instead of requiring you to use a programmer cable. This is an open hardware project, so you can either build it from scratch or purchase a kit from the adafruit store – YBox2 – DIY Networked Set-top Box.
