Can you install Mountain Lion on multiple computers?

Yes.

 

Yes. It's in the agreement you skipped.

Lion's agreement was something like "all the computers you control". I've heard ML's agreement was something like "up to 3 computers" but I skipped reading it too.

 

If you bought it through the App Store, you can install it on all of your personally owned Macs.

 

Since you both skipped it, the agreement actually doesn't limit the number of computers, only to the computers you own or control. The Mac App Store Terms and Conditions govern this, btw, so it hasn't changed for Mountain Lion, and applies to any application you download from the MAS, regardless of the developer or type of application.

As long as you own all the computers you install ML on, Apple probably won't even care.
