BVR 'Beyond Visual Range' Relays are global mode SDK applications that use console messages to relay a persons chat beyond the usual 400m cuboid visibility limitations imposed by the world server. This features has gained popularity in recent years and is now featured in most Public Building Worlds, as well as many private worlds.
Notes: None of the listed bots is known to fully support SDK build 100 / version 5.2 or later features of the integrated chat channels, although they run with the backward compatible SDK build 100 without recompilation from source. Most chat bots are known to break features built into the system, e.g. likely the 'mute' feature and timestamp display.
