This includes the MSDN version, although as mentioned above you get 10 keys. Presumably each key can be activated on up to 10 computers (that's how most MSDN software works) so that's 100 unique computers all up.
As a side note, Safari kept crashing when I tried to download this yesterday (it'd get to ~60% complete then just crash). I ended up having to download using Firefox. Also, for some reason the ISO file contains a DMG file. If you're going to burn to DVD, make sure that you mount the ISO first and then burn the enclosed DMG.
