I'd like to say thank you to Rambo. You've made possible what i've needed for so long. Following the instructions on the project page. I was able to tether from the ipod touch to the n900's 3G without any reboots.

And I say Thanks again.

(Note: You might want to add to the instructions, that the .py script should be made executable. ex. chmod a+x hotspot_frontend.py)
