Has anyone used a "Self-Directed" IRA or 401k to purchase Thai property?

I use self-directed retirement accounts for real estate investing in the US.    I was reading that the IRS does allow foreign real estate purchases inside self-directed retirement accounts, but that some other countries take issue with it when attempting to make a purchase.  Since I don't have a Thai wife, or the desire to have a Thai business partner, I am strictly looking at condos, and I find them all over priced, but when the market corrects back to reality I would like to be ready to move when I spot a deal.  

So, my question is, has anyone successfully used a self directed account to purchase Thai property?

Thanks!
