It would be a nice addition if we could interface ComputerCraft computers with the Matter Transmitter and/or the Dialing Device.

Open Computers is supported. Is Computer Craft still active?

@SquidDev forked the original CC and is keeping it alive as https://minecraft.curseforge.com/projects/cc-tweaked

As far as depending on CC goes, there are unofficial Maven servers for ComputerCraft and my fork. That being said, I believe the former's mappings are positively ancient (they haven't been touched since I did the initial port last year), so you may have issues with that.
