I have the same problem with my Mac, either Honeycomb on a SD card or rooted stock. It was working for both initially, but no more (??) At least I was able to install the market. After that I couldn't get adb to see the Nook.
I installed the Dropbox app and used dropbox to copy the adbWireless app to my Nook. Using Root Explorer I then was able to move adbWireless.apk to /system/app. It was a bit of a pain to do that, but now ADB works great for me via wifi.
