It seems like Google decides what to show by IP address - not sure if it based on history of queries from that IP address or based on location of IP address. The same query from my college's day work (just a couple of miles away) gives different results.
Build a seeks node, http://www.seeks-project.info/, configure it to only use Google search as backend. The both of you can then use the Seeks frontend instead of Google, and you'll get the same results.
Additionnally, you guys will benefit from each other's actions on results.
