We have a suite of dating websites that raise various alerts and notifications. It's fine when the user is on the Site, but when they're not we'd like an app to sit in their tray/launchpad that polls the site(s) for any new notifications, if found, they are presented to the user.
There are three parts to the app
1) install and settings configuration.
2) tray icon and context menu (and Mac equivalent)
3) notification popup alert, MSN Messenger style when a new notification is present in the recent poll results.
More details and some proposed wireframes can be found in the attached document.
