I am working on a port of Sidoh's AE2 Stockpile program, originally for ComputerCraft. It allows for keeping a specific number of items in stock in an AE2 system, and has the ability to add and remove items without the user having to edit configuration files.

I am porting this file by file, so watch this space for new i
