Yay, internet! Of course, I know it's not the same...
As to your children finding true peers: they may or may not find peers in the community, but they will find individuals who share certain aspects of them, and putting together their various relationships, that will be enough; no one person can or should be all to any of us.
And your boys have each other. Believe me, those relationships will be enormously important, and ultimately supportive, not only for the usual family reasons, but because, with all their learning distinctives, they are still likely to be more like peers than most others. Plus, when they someday have gifted offspring, they'll be able to share the experience with each other. =)
