I recently picked up an Arduino and outlined how to use a serial connection with the Arduino and python on my weblog: http://www.postneo.com/2007/01/18/arduino-serial-communication-with-python. Talking to serial devices can be a little easier than I outlined on a Unix-like system, but I like the cross-platform nature of PySerial: http://pyserial.sourceforge.net/.
I just thought I'd share in case anyone else was curious about interfacing the Arduino and Python.
Though it appears that your website has since been replaced by a landing page for GoDaddy. Not sure what happened.
You might consider posting the tutorial or a link to it in the Arduino playground, interfacing section: http://www.arduino.cc/playground/Main/Interfacing
You can create an account at: http://www.arduino.cc/playground/Main/LoginForm
I'll put the information up on the playground later today.
The godaddy landing page is a bad combination of timing, a domain transfer, and the inability to log in to my account to set up DNS records. I'll get that fixed as soon as I can though.
Here it is:
I'm also trying to migrate hosts, so I understand a bit of what you're struggling with.
