Looking For Rank Checker for Previous Dates

Is there a tool/software/script that can check archives for ranks.
What I want is type in keyword and url and get rankings for the past.

For example

example - example.com
9/1/2011 = 4th
8/1/2011 = 17th
7/1/2011 = 21th

etc

anything like that out ?

Thanks in advance

ideally you'd need a time machine

rank tracker by link assistant allows you to analyze historic records (rankings on previous check dates). if you never checked for rankings with the tool, archived data will obviously not show. curious what others respond to this - perhaps there is such a tool out there..
