STEP 1 : Locate your Rei's Minimap markers directory (\.minecraft\mods\rei_minimap\)
STEP 2 : Rename your most complete Minez .point file to "minez.points"
STEP 3 : Remove all your other points files (or backup them... or merge their contents using notepad...)
STEP 4 : Save the following lines in a file called "create_links.bat". Save it into the markers directory.

@echo off
mklink /H us1-public.minez.net.DIM0.points minez.points
mklink /H us2-public.minez.net.DIM0.points minez.points
mklink /H us3-public.minez.net.DIM0.points minez.points
mklink /H us4-public.minez.net.DIM0.points minez.points
mklink /H us5-public.minez.net.DIM0.points minez.points
mklink /H us6-public.minez.net.DIM0.points minez.points
mklink /H us1.minez.net.DIM0.points minez.points
mklink /H us2.minez.net.DIM0.points minez.points
mklink /H us3.minez.net.DIM0.points minez.points
mklink /H us4.minez.net.DIM0.points minez.points
mklink /H us5.minez.net.DIM0.points minez.points
mklink /H us6.minez.net.DIM0.points minez.points
mklink /H eu1-public.minez.net.DIM0.points minez.points
pause

STEP 5 : Run create_links.bat.

This will create hard links, all pointing to the same minez.point file. All your points will be the same on every MineZ server !
