Not a real binding but it works:

<TextBox Name="scrlTB1" Height="100" ScrollBar.Scroll="Scroll" ScrollViewer.VerticalScrollBarVisibility="Visible"/>
<TextBox Name="scrlTB2" Height="100" ScrollBar.Scroll="Scroll" ScrollViewer.VerticalScrollBarVisibility="Visible"/>

private void Scroll(object sender, ScrollEventArgs e)
{
    if (sender == scrlTB1)
    {
        scrlTB2.ScrollToVerticalOffset(e.NewValue);
    }
    else
    {
        scrlTB1.ScrollToVerticalOffset(e.NewValue);
    }
}

(This example ignores the possibility of horizontal scrolling)
