Not sure if I'm in the right spot, so if I'm not, point me in the right direction!

We're getting married next August (2012) and we started playing around with our guest list last night. I think that's when it hit home for my man that his autistic brother would not be able to be a part of our wedding.

He cannot speak and must live in a group home, he is not very high-functioning. He is 21 years old.
Does anyone have any ideas on ways we can include his brother in some way? It doesn't have to be on the actual wedding day, I don't think, but we need to do something special.
My guy kept saying "its just not fair" through his tears last night and it broke my heart. I'm determined to make this a special day for EVERYONE in our families now!!
Thanks in advance, everyone
