Thanks much for clearing this up for me.  I'm obviously not a DNS 
expert.  Now that I understand better I see I was wrong and it will be 
possible to algorithmically avoid querying the TLDs.

So, my concerns surrounding #4 and #5 were based on a misunderstanding 
on my part which is now cleared up.

Thanks again!
