Multiplayer would have been amazing, and really added to the games longevity.
Just looking that the files, its a mess, downloadable content folders, lack of organization, cryptically names folders and files.
Is the PC version a converted 360 version?
Some multi-player powers I found
A "Team Heal"--Heals members of your faction within 15 meters by 50 percent.
Felucian Warrior Summon--Summon a Felucian Warrior that will resurect dead players and attack enemies of the player.
Shadow Guard Summon--Summon a random ShadowGuard type and attack enemies of the player.
Storm Squad--Summon a squad of stormtroopers that do your bidding.
Other (was in the test code but was commented out)
Tie Bomber Run
Star Destroyer Bombardment
Holocron Gather (JO anyone?)
By the looks of the files they had a working multiplayer or were close to making one finished
Don't ask me what any of this means, this is all taken from Lucasarts code (even vampire attack)

Edit: The frame rate is set (at 30 fps) in AnimSystemOptions.animoptions.xml in Scum/Runtime
Good news for those with high end graphics cards
