- multicast backbone — (MBONE) A virtual network on top of the Internet which supports routing of IP multicast packets, intended for multimedia transmission. MBONE gives public access desktop video communications. The quality is poor with only 3-5 frames per second instead of the 30 frames per second of commercial television. Its advantage is that it avoids all telecommunications costs normally associated with teleconferencing. An interesting innovation is the use of MBONE for audio communications and an electronic "whiteboard" where the computer screen becomes a shared workspace where two physically remote parties can draw on and edit shared documents in real-time.

- objective modula-2 — (language) (Or "ObjM2") An extension to Modula-2 for Cocoa and GNUstep software development. Objective Modula-2 follows the Objective-C object model and retains the bracketed Smalltalk message passing syntax used in Objective-C. Classes written in ObjM2 can be used within ObjC and vice versa. ObjM2 also retains Modula-2's data encapsulation features, namely nested modules with explicit import and export lists. Due to the strict type checking in Modula-2, ObjM2 can be considered a much safer programming language than is ObjC, yet losing none of the capabilities of ObjC.
