So i was thinking today, with all the signs i have on my spawn for first timers; What if it was possible to remove the client lag cause by signs? md_5 implemented a view distance per world, so i assume it may be possible to prevent signs and certain other blocks from being sent to the client with a configurable view distance. How would it work? When a player is x amount of blocks away from signs or another block, they will not see them until they are within the defined range set in the configuration/bukkit.yml so signs and items frames or other blocks will no longer cause fps lag for players with bad hardware. Of coarse if this were possible, there would be many other things that can be added to prevent certain blocks and or entities from being sent to the client. I have no idea if this would be possible, and if it would have an impact on the servers performance, but if you can manage to get this working i myself and I'm sure many others would love it..
