Sorry I was slow to reply. Some very good points for an against here. It
seems a lot of kids are getting advice from you tube sites to use Hamachi.
Yes it does create a VPN tunnel, I suppose the best thing to do would be
setup a machine configure Hamachi and then go find yourself a good
(friendly) hacker somewhere and ask them to join your hamachi network and
see if they can access things you dont want to be accessed.
Its a tricky balance between being a "grumpy dad who wont let us setup a
mineraft server" to being cautious and trying to protect other machines and
our home network.
Ive tried explaining that even if you had a fantasic minecraft server at
home with lots of CPU and memory, the incoming players will only get a
shared connection speed of your upload bandwidth which is usually quite
slow on ADSL broadband and will affect their overall responsiveness. So its
probably better to investigate online minecraft server hosting packages.
All of this is usually met by blank vacant stares anyway...
