As described in older XGOX Forum at bitcoingarden, there is a possibility to create an unique XGOX address by using an Software called vanitygen.

This Software is opensource and seems to be save. You should use it offline, but you need an fast CPU or GPU (or many). You can find a lot of Info to this Tool in Google. Special Parameters for XGOX I can post later.
Dont use some online tools and dont buy an private Key from others. Create the addresses offline for yourself.
Stay creative, people!
