I have yet to determine the d20 System's equivalents of the LUGTrek skills. Some of those skills should be converted to feats instead, IMHO.
I am currently using D&D3e and Star Wars d20 as reference. I would like to see how the upcoming Traveller d20 (or T20) rules deal with prior service background.
<font color="white">Off the top of my head, one LUGTrek skill level should be approximately equal to two d20 skill ranks.</font>
I'm also toying with a radical concept based upon the prestige class rule mechanics called promotion class (tentatively titled). It's a set of one-level "prestige classes" that determines your standing rank. Just like a prestige class, you need to meet the requirements. And high-ranking promotion class would definitely require low-ranking promotion class (e.g. a Lieutenant promotion class requires the Lieutenant Junior Grade and Ensign promotion classes). Don't worry, there will be a promotion class rule mechanics for enlisted personnel, too.
(I'm also toying with the concept of Officer-level benefit based on the Epic-level rules mechanics for comparison of two different approach to promotion ... and see which one is better.)
Like I said, it's a radical concept that character do not need to spend a feat for it (I know a lot of you are thinking of using promotion as a feat).

Anyhoo, just some random thoughts...
