About this project
What does Roughly Enough Items Server Component (REISC) add?
Roughly Enough Items Server Component is a mod to implement the REI server networking protocol to handle server-specific features.
This is intended to be used on servers that want to keep having JEI on the server, while allowing clients to use REI as well!
IF you want to fully commit to using REI, simply download the full REI.
Should be extremely harmless to servers as REI is extremely efficient, my testing on E6 servers is about 300ms off-thread.
Features
Allow REI clients to use Delete Items (without in creative mode)
Allow REI clients to cheat items (without using creative mode / using NBT length limited commands)
Allow REI clients to move items
