There's another reason to get rid of the ArsDigita in the name of the project. At one point I remember we were afraid that the VCs would come after OpenACS if something happenned to the company and they were looking to sell the intellectual property of ArsDigita.
While it's a good thing to pay homage, and I think we have an obligation to keep a history of the project to acknowledge the hackers at ArsDigita who worked hard at the toolkit, there are legal considerations here.
