Slowly but surely, progress is being made. I have the infrastructure of a driver up and running, courtesy of a comination of romfs, ext2ifs, and the Nagar sources. For anyone out there who is looking for an updated version of the Nagar sources that will run on WinXP, I've put it in CVS (I'll try to remember to tag it). Meanwhile, I've figured out how to recognize a ReiserFS partition, mount it, and handle the IRP event model well enough that Windows won't bugcheck. Next I'll begin working on reading the directory structure, and some usable code will start appearing in CVS.
