Possible to tether with OS X Leopard?

search for wifirouter works awesome, turns your mogul into a wifi adhoc network and shares your internet connection to your mac. I use it with my macboo pro all the time. works like a champ. I use it in the airport so I can surf on my mac without having to pay for the airport wifi.

also it's much faster than bluetooth. There is a way to do it with bluetooth, i got it to work...once...but it was a pain in the ***. with wifirouter I turn on the app, select the network on my MBP and surf away.
