LSL Protocol/Restrained Love Relay/Introduction
The Restrained Life viewer is an alternative to the Second Life viewer, mostly aimed at enhancing BDSM play. It is aimed at making restraints more secure and more restrictive, by giving the "top" more tools to keep the "bottom" under control.
It is operated through llOwnerSay calls in LSL scripts, by reacting when the message sent through this call is formatted in a special way. However llOwnerSay is obviously limited to objects the user of the viewer owns, mainly attachments.
Restrained Life Relay
Additional support was added to enable objects such as cages, furniture and so on to also disable functionality. This support works by communicating the commands through a script associated with the avatar (controlled by the viewer). This indirection is frequently described as a "relay".
Discussions in SecondLife either talk about "relay" or use abbreviations such as "RLVR".
The documents associated with this portion of the wiki discuss the "relay" or Restrained Life Relay API.
