Actually no, I don't think you do need that. You could have them all on the same frequency, you just need to change the "sub-net" thing.How well does logistic pipes interact with tesseracts?
Tested it myself, it works flawlessly with one minor draw back. You can only have two tesseracts on the same frequency. You can't for instance use 4 tesseracts going to say a farm/furnace/mining/crafting. There is a work around though, you can simply chain them, requires double the amount of tesseracts but thats w/e.
Farm > tesseract freq 64 > furnace tesseract freq 64 + another tesseract with freq 22 > mining with freq 22 + another tesseract with freq 88 > crafting > tess freq 88.
So with the above setup if you wanted to take something from your crafting tesseract to your farm it would need to go through all of your previous tesseracts. (88 > 22 > 64 > farm)
Farm - Freq. 84 entitled "Farm"
Freq. 84 "Farm" - Furnace
Furnace - Freq. 84 "Furnace"
Freq. 84 "Furnace" - Mining
Mining - Freq. 84 "Mining
Freq. 84 "Mining" - Crafting
Crafting - Freq.84 "Crafting"
Freq. 84 "Crafting" - Storage
Still uses the same amount of tesseracts as you have mentioned above, but it keeps it all on one frequency. Useful for servers that say you can only have frequencies "85-87" or something like that
