Udk can support 128+ players?

i am devoloping game but i see most games not support 128 player servers(project reality 100 players) udk can support 128 players ? what is the problem why developoers or game companys not support ? in udk we can we make 128 players support with stability ? (i think sending playerid.location,direction,headdirection if inventory changed i send invertory changed items with array, i want send voice talk,messages,firinggun,mainweapon (if changed) )

this is to hard to do for 128 players server ? and udk can solve that problems ?

sorry for my bad english :frowning:
