SJ didn't say it should be in the same
group as Crystalline tech, but the same
style of the Energy Lens, which is a part of Crystalline tech. The Energy Lens provides, IIRC, a +60 shield bonus to all ships/units with shields in a system. An equivalent propulsion Version -- which could be either normal tech, or perhaps tied in with Propulsion Experts (or both, with P.E.'s getting a more powerful Version) -- would provide propulsion bonuses to all ships/units in a system/sector. I'm not sure if there's an ability for that though, I'm not too familiar with all of abilities.txt
And I remember being able to send packets of the three kinds of resources in a Stars! demo... IIRC, you needed a special component to launch it, and the same component to catch it (if you actually wanted to catch it). I remember a few times arranging for the packet to arrive at the point an enemy fleet was expected to arrive at, when said fleet arrived... destroyed the fleet. Also remember flinging a very big one, very fast, at an enemy colony... and I had a transport ready to colonize the newly enriched and now empty planet. Ah, that was fun. SEIV is better, though
