First off props to indirect, this is a huge step forward. Had a few issues, like needing to update superuser to latest build since it kept fc'ing. Other than that it works perfectly now. Also have android market now up and running on my nook tablet. It works great so far, but haven't tried movies or buying anything off the market. But apps install and run fine. Same install method for the market as the Kindle, you can follow this guide here:

edit:

Oh here some tips if you guys run into trouble with the script.

If the script doesn't work you can clean up the directories as well as uninstall superuser with:

adb shell rm /data/local/tmp/*
adb shell rm /data/local/zergy
adb uninstall Superuser (or manually uninstall it with an app manager)

then run the script again. If that keeps failing then just manually past each line of commands into a cmd prompt. I actually had to do that, script would not work for me. After that, I updated to the latest superuser since the one that comes with the zip file kept force closing, but that could be a problem that's unique to me. I was too lazy to restore and already had a ton of 3rd party crap on my tablet lol. I might also do a video when I root my friend's tablet as well. Anyways, hope this helps!
