I do want to mention one thing -- to him and his wife, but perhaps of interest to others -- or not. The have an 18 month old son. Since we didn't really plan anything there was a lot of hanging out around the house, and I got a definite feeling being there. My friend and his wife are totally focused on and madly in love with their son, and they've arranged things so that they spend every possible minute with him. This kid is going to have several years of a life feeling totally loved and secure, with everything in its right place.
This is an inestimable gift they are giving him, and as their friend I feel really proud of them.
