you can not speed hack in runuo - if the packets come back to fast/to far away, etc etc, it rubberbands them back to origional spot slowing them down
it might help those on a slower isp/modem to be as fast as those on good isps/modems, but can not go faster than the server allows, it is built in to check for it
and if they are trying to use 4.11.c on a 6.0+ shard - they can't, if you set it up like a said above - if the tram map is different via either statics, map itself, etc where you have them start off at with new toon, they can not move then, becaue it will be black to them (make sure no spot on fel map is there)
also since there is no "dif" files for them to read (and you can patch empty ones as part of your patches also to mess them up), the tram map again will not be correct - i.e. start them in haven on the bridge which in fel is water - of course i am talking old haven bridge if it is still there (or make your own and freeze it to the tram map and patch it to the players)
and like i said, make new items so they have to use your tiledata, and then can't use 4.11.c because it does not reconize all the points in the updataded one, and they can not dress armor and such because they have invisible crappy armor on (visible to those that can read tiledata) and thus can't remove it
