Class file question

[Mr Josh Pearson]

Hello guys,

I hope im in the right spot for this so here goes

I am trying to add some mods to my server but i have a couple ID conflicts, they are easy enough for me to change in the cfg file but this has to be done client side as well.

So what i would like to do is install the mods to my server and then use a custom zip in tekkit launcher and i have done this but i am wondering if it is possible to edit the class files with the updated ID's for my server so it dont have to be done client side. basicly doing it for them.

if this is not possible then is there anyway to use the custom zip in tekkit launcher and have it write the cfg for me client side so the user dont have to change anything?

i hope i have worded my question right or explained what im looking for.

thanks in advanced for any replys
