Peter says it very well. The idea behind the W1 drivers seem nice, a unified abstraction layer hiding the adapter type. Unfortunately it will be linux-specific (not too great a problem), and is undocumented. A greater problem is that each adapter type has different strengths. A better search routine, different in-band/out-of-band signaling, etc. OWFS has evolved to use each adapter efficiently, for our usage pattern. A kernel-based driver would not know when to reset, for instance, since it wouldn't know which thread of OWFS was grabbing the adapter. I suspect that the kernel driver would not be as efficient. Currently W1 is only relevant to USB. OWFS unloads the ds9094r kernel driver and uses libusb, so you really don't have to make any changes. When W1 is finally documented, we will see about supporting it. I am most interested in W1 for direct bitbanging interfaces in embedded systems and the Matrox video card.
