Abyssalcraft has an energy called "PE" and Silent's Gems has an Energy called "Chaos". Project E has a thing called EMC. I think it would be cool to see those as possible energy sources for machines.

I'm sorry if three is too much to suggest at once, I guess I just wanted to put these possibilities out there.

Added to my todo list.

Regarding the EMC support, my solution which works now is to ProjectEX Personal EMC Link or Refined EMC Link etc to consume/produce items into/from EMC using item pipes or hoppers into Modular Machine item i/o hatches.

You can then setup any recipe you want e.g. Blood Magic Life Essence LP to/from Dark Matter for example... (or any items that have the EMC value you want for the recipe)

I love all the possible combinations!
