Permanent computer-to-computer (ad-hoc) network

[Shadower]

Do anyone know how I can create a wireless computer-to-computer (ad-hoc) network that doesn´t disappear everytime I reboot my Mac?

I use the "Create network" option in the Airport menu to create it, but is it possible to use Terminal and then create a script?

Thanks!

Also having this issue...

I have tried setting up my friend's iPhone to tether to his Macbook Pro using the Tether app available on Cydia. He has a 3GS iPhone on 3.1.3. I jailbroke it for him, and was trying to create the ad-hoc network so that he can use this program to tether. I followed the instructions on their website to the letter, but when he disconnects the iPhone, the ad-hoc network he created disappears, and he is then unable to use tethering again without redo-ing all the work I did at the beginning. Can anyone help with this issue?
