Essentially your storyline is to build your reputation and break your programing. You could meet other droids both pathetic slave master droids or ones similar to yourself.
I'd like to see something similar, or perhaps something more along the lines of finding upgrades for yourself. Some story-line quests could take the shape of you uploading yourself on the holonet (this could happen on let's say Nar'Shadda) finding the most resent of Software or information that you can use. The later part of such a quest could make you enter something like the Spirit World on Voss only that instead of Nightmares and Corruption you fight Firewalls and Viruses.
