I'll test it if you want, I can throw up a private server for us to test on. If you wanna look through the server's source to make sure you have all of the packets required to control movement then heres the latest SVN (updated pretty frequently, just look for the highest version number). You'll also need the cygwin files put in the directory with the .exe's

Keep in mind that there is two movement systems, eAthena type and Aegis type, not sure exactly what the differences are but Aegis is used by official servers. (kRO, iRO, etc) while eAthena is used by the majority of private servers (agRO, andzRO, my server, etc)
As far as I know the eAthena is just optimized to reduce system resources used, but increase network bandwidth used as the cost.
