No, it's not about sparring with biters. 
Latest scientific researches discovered that if you put some goods into strong enough box made of steel and plastic,and jump a bit to fit a little more, then result can be transported on transport belts, placed into boxes and in general behaves like an item!
However only basic items can be boxed. More complex and as a result more sensitive goods are breaking on jumping phase.
Update: After endless thinking, jumping and experimentation with sole, boxing scientists discovered some improvements to boxing technology.
Namely - boxing technology 2 aka advanced boxing! With this technology you can box even more stuff and even craft some circuits without unboxing ingredients!
Somewhere on the way recipe of steel box was optimized and box costs 3 steel plats less and have crafting time of 0.5 sec.
Steel box recipe:
1x steel
1x plastic bar
Items that can be boxed and unboxed:
50 coal, iron or copper ore
100 iron or copper plates
200 copper cables or electric circuits
Require boxing-2:
100 plastic bars
100 steel plates
100 advanced electronic circuits
Stack size of boxed goods is 10. Boxes are retained on unboxing.
Jumping was proven to be inefficient and inconsistent, therefore boxing and unboxing can only be done in AM2 and AM3.
After researching boxing-2 following two recipes are available:
2 boxes of iron plates+3 boxes of copper cables=1 box of electronic circuits+4 empty boxes
1 box of electronic circuits+2 boxes of plastic bars+2 boxes of copper cables=1 box of advanced circuits+4 empty boxes
With this mod central bus concept is a little more viable
Also, this mod makes 'mostly robots' factories designs MUCH more efficient.
I tested this mod. It contains only new items and recipes. No problem found. So I moved it. -- ssilk
