Support for JABBA Barrels?

I'm using the Techworld 2 FTB pack and i'm trying to figure out some way to have a item/block calling system with computers and the JABBA barrels. Is there any way to do this with, say, MiscPeripherals? If not, is there something else that I can use?

Nope. MiscPeripherals has never done anything like this. OpenPeripheral adds support for any blocks that use the IInventory interface, so you could check with OpenPeripheral installed if you can interact with them, however if Techwold2 already has OpenPeripheral installed then you're definitely not going to be able to do anything with JABBA barrels. OpenPeripheral is your only chance so I'll talk it over with the guys and see what they think about adding support for JABBA barrels.
