Gas can be handled by this terminal. I will be looking into Mekanism and its gas system though and if its feasible enough, I'll just make a compat if necessary to make Mek gases function as fluids in AE2. The issue is that Mek and a few other mods don't use Forge's "gas" system (and I do not blame them). But that makes it more of a hassle for other devs to support their proprietary systems.
