Hamachi. We all know it's useful. One of the guy's suggested implementing jj2+ with built in hamachi. This would work quite nicely, if it had it's own virtual network. Like basically, a + hamachi network that is connected to upon start jj2+

The only downside is that non-plus users cannot join. But it would definitely contribute to the number of abstract servers and give those who couldn't normally host incentive to go out and create levels to show off in their own servers. More servers would draw a bigger crowd.

This is a really good idea! Definitely take it into consideration. It would also stop people from whining that they can't host :P
