Two serious limitations found :
1. Your link cards use absolute, not relative coordinates. This means that when you move a setup of extractors/capacitors/projectors using frames, they quite working after being moved. And, it's impossible to automatically re-establish the link. If the link cards stored the relative coordinates between blocks (when installed they update to reflect the relative position of one block to the other) they'd keep working.
2. The extractor exposes only 1 slot via iSidedInventory - the slot forcium goes in. This means it is impossible to convert EU to force energy automatically.
