Dante 
Hi, I need to develope a program for an industrial HMI. My question is about the use of xubuntu for my commercial purpose. ¿Can I use it for this purpose without legal problems?. I have read many documents about type of license, but i realy don't understand to much, it's very confussing. I hope someone could help me. I also think about using android for my work. The same question. I also have to mention that i can't afford an expensive license yet, i'm just starting in this business by myself. I would appreciate some help thanks
