Yes, Asperger's is tough. We live in the United States, and homeschooling is quite easy to set up. You just have to file your wish with the government and then follow the curriculum the state has adopted for the ages and grades.
I worked with Asperger's kids for many years. I would think that homeschooling would be a good set up for him. For one, he would not have to spend 6 hours in a classroom, 2 he can take as many breaks as he needs.
The usual concern is socializing. Here, there are many homeschool groups that meet up so kids have activities (like skating, or a dance, or sports) and they can meet others. In all my years as a special ed professional, I have seen homeschooling work wonders far more often than not.
