LAN Server. Can I do this?

[LaZZer]

Hello,
I just got my own server running last night and I was having a great time. Making my own items, summoning NPCs, Ice Cometing them. Makeing my level 99 warrior with max stats. So I called my friend and told him about it. He suggested that we duel each other in the emu. Can I do that? I have 3 computers on my network. Can I have them connect to my server or does minilog only support one account? Also is there way to populate a zone with NPC's when I zone in? I mean like zone into Qeynos and have all the little rats running aroung and the guards there. Even if they dont do anything I would still like to raid the zone.

Thanks for your help,
LaZZer
