If you mean send items between your Jedi and your Sith, I don't think you can.

Really loving it. It's not perfect, but then perfection is overrated as my favourite Twi'lek points out on a daily basis even as she brings me exactly what I asked for... My only real complaint is the horde of blocked off areas. I really think they should've used some sort of phasing type approach ala WoW (as buggy as it can be the idea is solid) instead of just straight up blocking large sections of the buildings off, or in at least one case an entire base: a base who's sole purpose is to have you run into it, deliver a message then run out. Damn thing takes 5-10 minutes total from ship landed to reaching it to going back to ship. Aside from that singular issue, it's a very good game all round. A really good blend of story and game play, typical Bioware really.

Having only a Sith warrior, it struck me moving from planet to planet that if the Empire just stopped being so damn lazy the direct/indirect wars on the planets would've been won long ago. Half my Siths lines involved her asking why the Imperials hadn't actually made good on their supposed gains only to be met with a half baked explanation ranging from lack of men to "one man can do what 12 can't...heh." From a game-play perspective it's understandable, but as a story...well I'd rather have an incompetent Republic that tries rather than a lazy Empire that doesn't. Sum up the Imperial tone seems to be one of remarkable ability countered by remarkable laziness. It's an Empire run by disinterested five year olds.
