Share Your Ideas voting module

I have a project listed on Freelancer today to develop a "Share Your Ideas" module which might be of interest to people here as well (or you might even be able to tell me if something similar already exists). It's based on something I saw at "Giveaway of the Day" where they use it to capture feedback on improvements from people who download free software.

What I want to do is:

• capture suggestions from site users about improvements
• have site users vote on these suggestions
• rank suggestions by the number of user votes
• maybe award a weekly or monthly prize for the most popular suggestion.

Does anything like this exist right now? Is it something that can easily be created using, say, Views and CCK? I think so, but not with my skillset.

If anyone else is interested in sharing the costs of this project and sharing the module developed from it, please contact me via PM.
