For anyone who is interested, the below code solves the previously unsolved problem. Current versions of OpenComputers add the .store method on ME controllers, allowing the storing of item information in a database for use with the export bus. In-world configuration has an adapter touching an export bus and an ME controller, and has a database upgrade in the adapter.

This code solves the problem of exporting one of each item, which I found of particular interest due to Thaumcraft's fancy new scan-everything-in-a-chest feature...

--Required API's
local component = require "component"
local serialization = require "serialization"
local sides = require "sides"
 
--adapter is connected to an ME controller, and export bus.
local me = component.me_controller
--export bus is has a redstone card set so it doesn't auto-export
local bus = component.me_exportbus
 
--adapter has an database upgrade
local db = component.database
 
--Loop over items in the me network
for key,item in ipairs(me.getItemsInNetwork()) do
 
  --print out each item for debugging; serializing to see the entire data table
  print(item.name.." :: "..serialization.serialize(me.getItemsInNetwork(item)))
 
  --Use the item as a filter to find an item in the me network, and store its
  --itemstack data into the database
  me.store(item,db.address,1,1)
 
  --configure the export bus to export that item
  bus.setExportConfiguration(sides.left,1,db.address,1)
 
  --trigger an export
  bus.exportIntoSlot(sides.left,1)
 
  --clear out the database entry. Might not be needed...
  db.clear(1)
end

Hopefully this is helpful.
