Here is an alternative Android application for checking who is online as listed by Dreamcast Now. The backend data used by the app is only updated once every 10 minutes so the listing might not exactly match what is shown on the Dreamcast Now website; I didn't want the server pulling the data to hammer the Dreamcast Now server too much.
* Main page listing users who are online
* Page showing currently played games with user information
* Sorting options for games page (alpha, number of players)
* Preliminary game event calendar listing with data from the Dreamcast Live calendar
* Local notifications for showing when a user is playing a particular game
