It's much more likely that some other approach will be > used. btw., what are the technical reasons why ndiswrapper cannot be done in userspace, much like the (wildly successful) FUSE concept? what's the main hardware access method of ndiswrapper - only PIO, or mmio as well? In the former case, ioperm() should work, in the latter case, mmap()ing the device aperture should work. Frankly, it would be a great approach for the following reason: it would be _far_ easier for people to write a proper free driver, if the NDIS driver was in user-space, in a nicely debuggable, traceable, observable environment. I dont really see what the technical difficulties there are here.
