OP again.
Since I "know" the people who had the house, I stopped by late yesterday and indeed, the roofers were using a Tyvek product that Red Green posted a link to way at the top of this thread.
Apparently they made a big deal about it in their estimate.
I only saw it from 90 yards away or so, but it LOOKED like the regular Tyvek housewrap with the big Tyvek name splashed all around. Again, follow the link Red thoughtfully provided at the top of the post.
IMHO, I would NEVER allow shingles to be placed without felt (or maybe Tyvek, now....).
