Write the abstrct class for hashing, write some subclasses that implement the hashing, and there you have it. For more exotic data types, of course the user needs to write their own hash interface - that is only to be expected. > I guess this discussion has gone beyond the point where it has anything > to do with FreeBSD... :)
