These are excellent suggestions, and ones that I'm sure Xiaoming Liu can
easily add.

But since you're on the line, I have some questions for you ;-)

1.  Do you have an official or personal opinion that you can share about
OAI & spidering?  

2.  DP9 is great for spiders that don't know any better, but what are the
chances of "OAI-aware" spiders?  Or is that such a special case that its
not worth accounting for...

Specifically, I maintain http://naca.larc.nasa.gov/.  Spiders are
frequently churning around in the tens of thousands of possible pages
there.  Of course, this is a good substitute:


but even better would be a spider that knew to use:
