This mod adds only one block, an "ME Capability Adapter", it basically allows Applied Energistics connections over things that proxies capabilities, such as Compact Machines 3 Tunnels.
Requires Applied Energistics 2, obviously. Not tested with Applied Energistics 2 forks (such as Applied Llamagistics), may or may not work.
Also requires Shadowfacts' Forgelin as the mod is now written in Kotlin.
Note: Requires one at both ends, also can only carry 8 channels. This is also something I made for my own use and thought that others may find it useful.
Update: The Full block version can now carry 32 channels, the bus version is limited by the cable it is on. So 8, but it *is* capable of handling 32 channels... assuming you can get multiple of them to link together.
