Okay, I realize what's happened. The right-click --> install on wimfltr.inf works. It didn't work on my nlited install of XP.
In order to get ImageX to mount without WAIK installed, you need to install KB914882. If you don't want to install WAIK or this KB, you need four files (fltmc.exe, fltlib.dll, fltmgr.inf, and fltmgr.sys). Right-click on fltmgr.inf and do install. You also need to right-click wimfltr.inf to install as well.
Once these are installed, do "net start wimfltr" to start the service and you should be able to mount.
This successfully worked in my nlited XP (which had failed before I did this) and this allows me to create a BartPE plugin that doesn't require the source to have KB914882 integrated. Here's an ImageX plugin for BartPE if anyone is looking for it: ImageX Plugin for BartPE
