Need Suggestions: cool CS internship projects

[lsman11]

Community,

Looking for some suggestions for a computer science intern project, mainly targeting the Windows (XP) platform. Looking for something challenging, so dont worry about the notion of 'a college level student cant do it'... these are the type of projects we want to challenge them with..

Once again, mainly targeting the XP desktop environment.. worker productivity ideas, innovation, buzz words, buzz words...

thanks!
