Unique Techonlogy and units

[The Odor]

Is there a way to simulate in SMAC/SMAX a techology that is unique to a faction, and unique units for it, that can be built?

Note I already know how to make new standard units and to give them at the start of the game to a faction.

Also I know how to assign abilities to a faction, like the Marine Detachment to the Pirates faction.
I want something that gives more uniqueness (like in Dune: Sonic tank for Atreides, Devastator for Harkonnen, Deviator for Ordos).

No, since the AI trades the tech away/it can be stolen. However, it has been requested, you can vote for it here: http://alphacentauri2.info/index.php?topic=14058.0
