gbox_applet is a GNOME applet which monitors several mbox-type mailbox files. Each mailbox can be assigned to a priority between 0 and 2 and it can have its own time interval for checking. For each priority there is a different icon. gbox can also count the mail in the boxes and show the subject/sender of each mail in the applet's menu. A tooltip shows a summary of the information in three different kinds.
The MPIO Project provides support for using Digitalway/Adtec MPIO digital audio players (DMG, DMK, DME, etc.) under Linux.

The local Message Bus (Mbus) is a light-weight message-oriented coordination protocol for group communication between application components. The Mbus provides automatic location of communication peers, subject based addressing, reliable message transfer, and different types of communication schemes. The protocol is layered on top of IP multicast and is specified for IPv4 and IPv6. The IP multicast scope is limited to link-local multicast. The transport protocol mechanisms ware defined in RFC 3259.
