That's some of the damn coolest things I've heard anyone done for years! Acctaully, I'm almost in the same position right now:
I'm going in school, officially, but I'm almost never there. I only go to the school every morning, hanging around with friends for some hours. Then I'm going home, telling my parents that we ended up a little earlier that day and rest of the day is spended with my beloved guitar. The schoolprinciple is trying to get me out all the time, but I found out that swedish law doesn't accept that students are thrown out, unless they are a threat to other students or doing nazi-signs and such ****.
So, I'm in some kind of sick middle land where I'm in school for the sake of my parents, but I'm not there.
Peace Sells... But Who's Buying?
