It scans for open ports on your LAN (more specifically your current subnet)
It stores the IP of anything that responded in an array of strings.
If you need one, here you go. If not, move along.
You can use the array of strings like I do for a server browser UI... or anything really.
Its not all that fully featured. It's just a port scanner thats been dll-binded into UnrealScript.
If you want to use it, go for it. Hopefully the code and the youtube video is enough documentation. (If the youtube video is unavailable, its still uploading/processing)
