I understand your logic behind the decision, but while it is true that
the details of wine's implementation of the 'encryption' is different
from that of windows', these details aren't a trait of wine itself.
Wine is an implementation of the Windows api, but the details of how
we do it should be encapsulated. What I'm getting at is that just
because this implementation is wine-specific doesn't mean some of the
implementation data should go in Software\Wine. Software\Wine is
where the configurations of the wine program itself, not its
implementation, are contained. See what I mean? btw it's great that
you wrote this code and submitted it. Sending the code in is the big
first step. I just think we should get a community opinion on this
matter (ya never know, everyone may disagree with me!). Keep up the
