So we have been through quite the journey...
Lets try this:
adb shell
su
which busybox (this will tell us busy is there and good)
mount -o remount,rw -t ext3 /dev/block/mmcblk0p25 /system
busybox ls -lrt /system/app/VZW_* (did this to check permissions)
busybox chmod 777 /system/app/VZW_*
busybox ls -lrt /system/app/VZW_*
busybox chmod 777 /sdcard/disabled.apps
busybox mv -i /system/app/VZW_Bit* /sdcard/disabled.apps/
busybox ls -lrt /sdcard/disabled.apps/
busybox ls -lrt /system/app/VZW_*
mount -o remount,ro -t ext3 /dev/block/mmcblk0p25 /system
exit
exit
WIN???
Ok so i've take a bit of time to reply and quite a bit has happened. Including me having a mental slip and moving "Htc*" to the sdcard! As you can imagine this gave me quite a few "forced errors". I freaked out and moved the Bloatware folder back to /system/app/ and restored to a prior date. Since I moved the folder back before restoring I lost the Bloatware folder. Amazing lol. Luckily, I had a restore point that was before I moved any of the bloatware.
So why am I willing to post such a silly error, because I think its important for everyone to see that mistakes happen. These mistakes aren't terrible as long as you took the proper precautions.
Now back to the moving. Even trying the way you posted above I'm still getting the same error, but interestingly enough most of the apps will move even though it says "operation not permitted". Also, when i use which busybox it says "not found", but when I do an ls i can see it in the folder. See below:
# which busybox
which busybox
which: not found
# mount -o remount,rw -t ext3 /dev/block/mmcblk0p25 /system
mount -o remount,rw -t ext3 /dev/block/mmcblk0p25 /system
# busybox ls -lrt /system/app/Htc*
busybox ls -lrt /system/app/Htc*

# busybox chmod 777 /system/app/Htc*
busybox chmod 777 /system/app/Htc*
# busybox ls -lrt /system/app/Htc*
busybox ls -lrt /system/app/Htc*
-rwxrwxrwx 1 0 0 37537 Feb 26 14:55 ←[1;32m/system/app/HtcRingtoneWidget.apk←[0

# busybox chmod 777 /sdcard/Bloatware/
busybox chmod 777 /sdcard/Bloatware/
# busybox mv -i /system/app/Htc* /sdcard/Bloatware/ (oops!)
busybox mv -i /system/app/Htc* /sdcard/Bloatware/
mv: can't preserve ownership of '/sdcard/Bloatware/HtcAddProgramWidget.apk': Operation not permitted
Ok, so aside from the oops line everything else lines up with what you posted. It says operation not permitted, but it moved it anyways. (To my demise in this case)
Once all the Htc* apps were moved I discovered the slide unlock that you see on the Motorola Droids. Not all that important, but interesting.
