I believe Hamachi was mainly a level 2 VPN, perfect for transporting IPX, which was really mainstream for LAN games of the 90s.

This seems to handle layer 2/3 since they mention support for TUN/Tap interfaces, but I guess 99% of people will just create IP tunnels, layer 2 is not the hot thing anymore.

Also, Hamachi was not decentralized from what I remember.

What is presented here reminds me a lot of n2n.

Some other apps in this category can also do layer 2, like tinc. It does layer 3 by default but you can switch it.

What would you use for layer 2 transport today(in spefific for playing ild games)?
