Ok, so you're importing ice. And you're importing or abstaining from meta modules. And you're importing either T2 modules and ships, or T2 BPCs and components, or T1 BPOs, datacores, and moongoo. You're importing faction ammo and faction/deadspace modules. You're mining high-end ores, exporting reinforced scraps and re-importing them as tritanium.
You're doing all this so that you can build a few things in a wormhole. You're still exporting and importing all kinds of stuff weekly, at a minimum. You're not very different from any other wormholer, except that you're spending less time looking for fights and more time doing logistics/industry.
If you actually want to produce anything significant in a WH, you're going to need several POSes, or just shittons of arrays that you constantly online and offline to switch tasks. And you're going to have poorly defended POSes that scream "shinies inside."
This was what I was looking for, thank you for the info.
