I think Stefan is correct. We need a good reason to switch the license version.
I also don't think the permission from just Vivid Solutions is sufficient. There have been a lot of other people contributing code to OJ. Our project doesn't require contributors to transfer copyright or the authority to relicense. That means we'd really need to contact all of our past contributors for permission to change the license. I know people have reacted coldly to the idea of asking for copyright on contributions before, but this very issue is one reason to do it. Still, GPL V2 has worked fine for us, so I don't think this is a burning issue.
