Why are you using an install program? Why not sign an applet and do something from there? Or use flash? Having a .msi file to install is a bit annoying. Also, your install should show some notification that it's complete. Currently, the install just disappears, making it tough to know if it even started.<p>Also, there is no background noise, so it's difficult to know if the program is working at all if nobody is talking (like in the HN room).<p>Furthermore, pushing the push-to-talk button causes behaviour I don't understand. The button pops up, then disappears again. What does that mean? Is it now on? I can't tell.<p>And finally, clicking the "Add room" button causes a strange message about the room that is not clear at all what it means. Am I now in multiple rooms? Do I own the room? If so, where is the list of rooms I'm in.
