Yes I did read that thread. Most posts are about not being able to do wifi or the upcoming tethering app by MuscleNerd and mostly crap talk about how the developer packaged the hack posted here and trying to make some money. Not much useful information, yet.
Well, Since I was one of the ones that posted on the other thread about the developer autorunning the commcenter hack, Ill throw my opinion out here as well! I think its great that the developer packaged the code, as I mentioned on the other thread, ssh is not for everyone! Im glad someone did it though! Its a great option to mywi and uses no where near the battery life! I have no intentionally tested the tethering while on a phone call, but can tell you that while I was tethered to my macbook, I did get a call and was on the phone for about 2 minutes and I never dropped my connection. I think you will be alright provided that you are on 3G network.
As far as a speedtest.net, I ran that the first time I went online with it and if I remember correctly it was around 2.62 down and .80 up.
I believe that its the exact same thing as the att tethering minus the $20/month fee!
