Not only are we rooted, we have superuser access on the working stock Thrive Rom (Android Version 3.1.01.5.0023)
(I'm only going by their IRC nicks in chat)
Or in a web browser
A HUGE HEARTY THANKS to the folks @ Tabletroms.com who helped!
(there may be others, chime in if you helped!)
And kudos to those that participated from Thriveforums.org

Also oe800 for porting Clockworkmod Recovery
1: NatolX bricked his Thrive attempting to flash the Xoom boot.img, proving we have an unlocked bootloader
2:austeregrim was the first to attempt a custom flash, but was the first to get Root (even if only in shell form by bootlooping his Thrive) his root allowed us to get deeper access to system and boot files, which then allowed for
3: oe800 to use Koush's tutorial to port Clockworkmod Recovery to the Thrive
4: The whole time the TabletRoms team was walking us through these steps and provided the modified boot.img
5: Dalepl was the second with root, but first to have it fully boot back and have Superuser permissions, and he also created the update.zip currently in use that gives us superuser
6: Mine is the 3rd with root, second with Superuser permissions in a booted Thrive, and my Clockworkmod backup allowed both NatolX (Tribute) and austeregrim to nandroid restore their Thrives back to life, no longer soft-bricked!
The Dev "DJ_Steve" at Tabletroms has been doing the most legwork for us, we are trying to donate so he can get his own Thrive. Hes being doing all of this without his own Thrive!
As donate links cannot be posted here, please visit TabletRoms Forums and thank the wonderful dev team over there for helping us.
It appears that we aren't FULLY rooted yet, we still can't r/w the system directory, but we at least have superuser permissions to do almost everything else, and a fix is being worked on to make it fully r/w.
Currently ClockworkMod Recovery is only temporary, although a fix is being worked on to make it permanent. It appears Toshiba reflashes its own recovery every time it boots.
There is another boot image that can be flashed which will allow the system partition to be r/w, we'll host that soon
there is a method to remove the Recovery-reflashing method, post can be found later in this thread.
