Interesting.
Yess the main problem is free-time-per-programmer-brand-users
i guess. Pentax has few users so the cumulative time of those who could contribute is much less. Even less of those who could do it at the same time, so the interaction and cooperation is low.
During the last week i had time only to create a project in DevCpp calling one function from CamCtrlV2-dll and mess with it like twice without any real results (except crashing windows - this scares me from connecting the camera).
I believe disable SDM is in the wish-list already (as well as in my must-have list before i purchase any SDM lenses).
So AF calibration from k20d in k200d would be nice as well.
