Revolutionary has been good at picking up and working up a root method for HTC phones to date - hopefully they'll do the same for the Rezound. Someone over at Rootzwiki claims to have full/permanent S-Off (see below), but so far nothing has been released but a screenshot.
With HTC phones you have to replace the "hboot" (basically like the bootloader) with one that is S-Off (security off - the stock hboot comes S-On). Then from the S-Off hboot, you can flash a custom recovery like Clockwork, and root and/or rom from clockwork. But getting that S-Off is the key. A lot of HTC phones can have temp root access pretty quick and easy, but permanent tends to be a bit tougher.
Unfortunately, Verizon isn't letting any of their HTC lineup fall under HTC's official bootloader unlock either...
