SimLink is a system for deployment and use of Java based downloadable plugins within the BuddySpace
instant messaging system. It also supports a mechanism to 'share state' in the group chat environment of
BuddySpace. This means that we can design a plugin whose current state is synchronized in all participants
of a group chat session. For example, one of sample plugins provided, allows participants to play a
networked game of Chess, and additionally progress of the game can be viewed by participants not
involved in the game.

In practice,
SimLink allows multiple users to share control of simulations and other software at much lower
bandwidth penalty than 'raw' screen-sharing would entail.
