u got a ton of good ideas but not all are viable for example
the fuel values cant be doen unless u decompile a mod addept it and send it to all clients wich is just not doable.
the gem generation u have to take into account that noone is allowed to mess with eloraams code. wich means u woud have to disable redpower gems completely cus theres no ore dictionary for them with gregtech gems wich would lead to no rp mining tools and no sonic screwdrivers able to be created.
this is btw also the reason in the first place why the rp gems drop instead of the gregtech ones
eloraam is not operating under a openGL licence wich just means if u screw with the code u can get sued.
the best thing gregorius coud do was this but if u coud find a way around this maybe adding it into the forge lexicon manualy by item id instead of making em different it coud be possible not sure tho.
for the tesseracts great idea but also not the complete story what do you do about enderchests ?
if u disable the enderstorage mod the vannila enderchest wil still be craftable and u cant disable that
without a recipe remover mod.
now the next point is disabling tesseracts and enderchest coud also lead to lag since people will make pipelines use myst portals with railcraft portalgun portals etc all of them wich wil cause more lag then a tesseract.
however u can change the amount of energy a energy tesseract loses in transportation to a bigger amount its 25% by default.
i never played with logistic pipes but if u think about the times it has to check chest inventorys and others i think it might be a burden on the ram i dont know this for sure but a big sorting system with these coud cause lag since if u got the itemsink modules it wil check each inventory until it finds one it can go in wich can take some checking if u got a huge factory for example.
i also know of bugs with this wich can randomly crash u if ur sorting system with em gets to big.
also redpower tubes are quite powerful with the new managers if u use em well.
i realy hope u dont take this personaly i like the ideas but some are just not viable from my point of view.
going on i would like to ask if the itemsearch mod gets added.
its a mod wich allows u to search nearby inventories for a specific item.
its realy small and a person can join the server without this mod installed altru he cant use the command obviously.
this is very useful when just starting out or when u got a massive base and got no idea where
for example ur wool went u do /search wool and it wil show a marker above the chest with the wool in it.
it has a default radius of 16 blocks to tamper any usage of for example pvp servers or dungeon finding with this.
(i coud change the radius in the code if u want me to since its open GL)
u can clear markers by doing /cs (ClearSearch)
its not realy a gameplay mod just a utility mod like nei to help u find ur stuff.
