Hi,
Can be done... Cambridge in the UK has an email list of Asperger's college students and grads.
Personal experience (been there done that, Aspergers, two engineering degrees, Masters, published articles and right now I'm heading the design of my company's next generation aneathesia machine and ventilators).
Well there is a lot of work to do so lets's get started. Sounds like your sons weakpoints are writing and social skills.
Writing:
So what has been tried in school for writing? Start getting some ADA accomodations and let your kid choose them. Only he knows how his brain works. With pen or pencil my writing level is 3rd/4th grade. On a computer or dictating to a tape recorder/computer (dragon speak) - - well, you guess the grade level. How does your son write (get him to describe the process)? I compose entirely in my head and then do a brain dump. Actually I see the words move as I edit and compose. Rocking back and forth and other such motions are really useful to help me do this efficently. My entire thesis was written while biking and rollerblading.
Social skills:
Always ask your son why. When there is an odd reaction ask what picture it causes. My husbund and I had this big fight over rewiring the house (I saw pictures of removing all the walls to replace wires. All he wanted to do was snake a few wires to an outlet box!!). The goal here is to help you understand your son's logic so you can adapt to it. I also find it helpful to mentally diagram interactions.
Good luck
