Question

So I would like to create an extension method for a Type that the api has otherwise sealed.

If you know about extension methods the following should look familiar.

private static List<Member> memberList = new List<Member>();

public static List<Member> GetMemberList(this GameObject go)
{
    return memberList;
}

Notice that to declare an extension method, it needs to be static, and because it needs to be static, the List that Im accessing through the GameObject type has to be static to.
I would like each GameObject to have its own list of Members. However Im pretty sure since this is a static field every instanced GameObject will point to the same static memberList.

So would my assumptions be true? And if so, what might be an alternative? I would like to avoid putting the GameObject in a wrapper class that also holds the memberList because the api only allows GameObjects to be detected and manipulated at runtime. There are ways to reverse reference the wrapper class through the gameObject but that adds a lot more complexity to the code i would like to avoid.

It appears you are working with Unity3. There is a related answer on the UnityAnswers site that may help: http://answers.unity3d.com/questions/22493/unity-3-sealed-class-gameobject-.html

It appears that there should be ways to attach the behaviors you want inherent in the Unity framework using the builtin scripting system.
