Yup, Visionary Root is the way to go, especially with the G2. I just put up a full how-to with a video on using Visionary for temporary root: How to (Temporarily) Root Your G2
I've also stuck with temproot for now, but am considering permanent. Thinking about holding out until the 2.3 update though because I've heard OTAs don't come once you switch ROMs.
I rooted using the unlockr method did it in about 15mins while at work.
You may want to think about root and flashing a custom rom now. True you won't get the ota but a custom 2.3 will be out months before htc does it. Also most otas break current root methods. Look at what happened with the evo or desire z(same phone as ours) ota came out broke root. Now people can't get it.
BTW CM 6.1 is sweet, CM7 will be sweeter.
