There are other WPS implementations for hostapd/wpa_supplicant and at
least one is currently in process of getting integrated into hostapd. It
would be useful to understand whether there are any larger differences
in the designs for these implementations and whether there are any
particular benefits in them to figure out what kind of combination would
be the best fit for hostapd/wpa_supplicant.

No new features will be added to the 0.4.x branch and I would rather not
add any larger changes to 0.5.x either at least not before they have
been introduced and tested in the current development branch (0.6.x). I
would assume that seeing the changes based on older versions would be
useful from the view point of being able to review the design, but the
changes will need to be ported to 0.6.x before they can be included.
