Asking for Hamachi to be bundled with JJ2 is pretty much unreasonable. I've said before that it would make sense for JJ2 to eventually have some form of built-in VPN capabilities, but truth be told, it doesn't make sense.

More plausible would be to have the listserver actually facilitate some of the tasks that a JJ2 game's host does. However, this wouldn't be a perfect solution by any means, and I doubt Nimrod wants that kind of strain on his network.
