Bill, You should not even need to install a program. From Android 2.2 on Mobile Hotspot is included in the OS already as is USB tethering... If you want you can also do it via bluetooth but I have never done that. Apparently its not as fast BUT it uses less power.
OK..so we have all had a little while to play with this Google+ thing.. Obviously its not finished but I think we have seen enough to answer a couple of questions... 1/ Whats your preference based upon their features today, Facebook or Google+ ?? 2/ Do you think Google+ could challenge Facebook?
