No problemo, good luck with your setup, ours is doing quite well
I suggest you set your item loader/liquid loader to only send the cart away when it's full etc.
use world anchors to keep both sides loaded.
F9per 9 world chunks. It keeps a 3x3 grid of chunks around itself loaded. If you press F7 (i belive that is the default) after you have placed the anchor you will see what chunks it will keep loaded
You don't need to go to the nether for lava, you know that right?
You can create an endless supply of lava pretty easily now....
