The "Missing" NXT Education Resource Set?

Back in fall 2006, I posted a query on this blog about the "missing" Education Resource Set from Lego.
The kit was available in the US for a few weeks last fall, but has been "temporarily" out of stock for five months at legoeducation.com.
The kit is now available in the UK, Spain, Australia and other countries but not in the US. Might anyone shed light on this mystery?

Thanks for this link to several stories about LEGO and their supply chain/outsourcing woes.
While these stories don't directly address a Lego "Resource Set" shortage, they do offer a plausible explanation of why the shortage exists.
Looks like I'll order my resource set from Europe (which was where my last set came from).
The report is a positive one about Lego as a company. However, the report talks about the supply chain strains Lego endures as they outsource farther and farther away from their markets.
Of course, outsourcing is not peculiar to Lego. But it may help to explain why certain Lego sets are in plentiful supply while others (like the Resource Set)are not.

When I ordered my set from them they tried to talk me out of buying it, saying that I could get it much more cheaply in the US. (That's when I explained to them that you couldn't get it in the US).
Any company that tries to talk you OUT of a sale is a good company.

about Lego's outsourcing is no longer working. Here's another link:

Do you know how can I get the Education Resource Set (9648) if I live in Mexico? I can't find the product here and internet stores (including Lego Education) do not have shipping to Mexico.
Thanks a lot.
