Changing the name will have zero effect on (mostly imaginary) confusion with AD product line. And all the possible confusion can be solved by a paragraph in a visible place on the web site.
Changing the name will have zero effect on the quality or popularity of the product.
That's not counting the negative effects of the name change (like confusing all those who already know what OpenACS is (to avoid confusing those that don't know?)).
I offer those insight despite overwhelming evidence that everyone else apparently thinks differently i.e. that there is any value in changing the name (therefore volountarilly setting myself up for a flame). YMAVBMMIB.
