I took a 2 minute look at your web site and I *think* I understand what it is. If I understood correctly, I should be able to take a widget that's hooked up to your back-end server underneath, and embed it in my web site to be able to gather feedback. The two requirements that immediately stand out in my mind are:
1. Is there a web site other than your own (even if it's owned by you or your friends) that's running this successfully without direct technical support?
2. Is the service reliable and free? (I could use Google Wave or Buzz instead)
3. How would you monetize this? (I ask because I wouldn't want my users' information in other people's hands)
