When I'm running Windows Live FolderShare, I'd like to know what machines I have up and running. I have numerous machines running FolderShare and don't always know which machines are up, so having a submenu off the tray icon would be very helpful. All I'm looking for is an informative list, so clicking them isn't all that important to me. Ideally, tho, this could be a trafficlight-style link, where green represents a computer that's online; yellow might mean the computer is online, but not yet synchronized or maybe the status hasn't been identified, yet; and, red would obviously mean it's down. Looking at it another way, disconnected computers could be disabled and the status identifiers could represent the sync process or something like that. Going the extra mile, these items could even link to the FolderShare website on the remote file explorer page for that computer. That would be pretty nice.
Edit: This has been suggested in two ways: a list of available devices with an online/offline status icon (green/red); and, a notification balloon message that pops up when another client changes status.
