This is an interesting setup, but there is not a lot of information I can discern about Stardust...

For example, may I ask what you mean by "a unique way of visualizing military combat?" There is no further information other than that allusion.

In addition, please forgive me as I cannot seem to grasp the same ideas you have. If I may, what exactly is a colony, system, fleet, army, agent, commander? 

Despite two colonies being cheaper than a system while producing the same amount of influence (and having a much less severe impact should one or both fall), what is the benefit of using systems over colonies?

What is a fleet / army comprised of? Is a commander in control of all fleets /armies of the nation or only one? Are commanders even used for fleets / armies, or is it a false assumption on my part?

How is espionage used? Does it consumed Influence? How would trade work in this Influence-centered RP?

Also, how would technology work? Are the players all of similar technological levels? Will there be advances in technology? Are people using projectile-throwing mass drivers, energy-cutting lasers, or magical Tachyon particle cannons? How do people move across the galaxy; FTL? Warp? Hyperspace?

Please forgive me if my questioning is an annoyance. This is an interesting setting and I've been interested in another Sci-fi RP for a while now, but as I said I wasn't able to figure out enough about how things work with what was given. Please excuse my ignorance.
