Dr. Matt and his kids love Minecraft and he'd "love for friends/family to share in the fun and play during lunch from work. Is there a way to (securely) connect to the server from the outside world? I was thinking it could work with a VPN... but I have no idea how to set one up. " No worries, Dr Matt... what you need is Hamachi and HOW TO SET UP A SERVER WITHOUT PORT FORWARDING (HAMACHI) from the most excellent minecraftforum.net. Best of all, you can use the same machine to browse securely any WiFi hotspot... check out How to Secure and Encrypt Your Web Browsing on Public Networks (with Hamachi and Privoxy)!
