The option is there to define custom profile fields for each member. These profile fields can even be set mandatory when registering. Tweaking the board templates a little bit, the information as depicted in the attached image could be shown for each member.
Different baan versions etc doesn't have to be a problem as these custom profile fields are of type string. There is no limitation as to what you enter. That can be good or bad
We could throw a poll on a yes or no for this option.
