And I got the WoD map working too. The nodes start at "TaxiButton1" and keep increasing from there.

If you don't mind, I might include this in my own addon as well. It seems like a handy feature to keep refining.

-------------------
-- TaxiFrame in WoD
 
local hooked = 0
TaxiFrame:HookScript("OnShow", function()
    local i = 1
    local button = _G["TaxiButton"..i]
    while (button) do
        button:SetShown(true)
        if (i > hooked) then
            hooked = hooked + 1
            button.Hide = button.Show
        end
        i = i + 1
        button = _G["TaxiButton"..i]
    end
end)
 
 
TaxiFrame:HookScript("OnHide", function()
    local i = 1
    local button = _G["TaxiButton"..i]
    while (button) do
        button:SetShown(false)
        i = i + 1
        button = _G["TaxiButton"..i]
    end
end)
