it seems that dplay_localfunction performs proc_local and proc_client both in a large scale. proc_local and proc_client effect only one entity function where as dplay_localfunction effects all entity functions, and also proc_local and proc_client do not affect the server where as dplay_localfunction does. so i would assume (to answer your previous question) is that depending on what you want it to effect would determine which you would use. i guess its a matter of memory.
