Mobile version VS. Dupe content

I'd like to have a little discussion on .mobi TLD's

I have been working on a mobile version of my site on the .mobi domain. I've gotten my plan ok'ed by vB to run the 2nd domain on the same license due to it being the same content/site.

Now, i'm concerned with getting dupe content problems with
site.com/thread/
and
site.mobi/thread/

does anyone know if google is smart enough to know about mobi domains, and can read the mobi DTD?

I've never come across a .mobi result while searching in Google....
