Quit being an ignorant troll and explain what errors you are getting in your server log.
Khaine's mods do work on multiplayer, you know how I know? I HAVE A MP SERVER RUNNING RIGHT NOW WITH THEM!!
If you arent getting them to work one of two things is most likely.
1) you just dropped the files from the zip straight into the MODS folder without drilling down one level, the first folder in his zips is not used, you hafta go into that first folder and put the next folder into your mods folder. For example you will have -> khaines-modlets-a19-master-KHA19-96BBMFW -> KHA19-96BBMFW its the second folder you want so KHA19-96BBMFW with everything inside that. In a mod the Modinfo.xml and file structure must always be in the first folder of the mod.
Or 2) You have your Mods folder in the wrong location in your 7Days install, it needs to be directly in the base directory of 7days.
Good luck and try not to be such a douche to the mod creators.
