Not sure if it's ever been discussed before but well I got a few ideas of my own as to what they could be...
First and formost I believe that each district should get a set of luggables, perhaps even different from the other districts.
Second, I feel that the luggables should be able to do more then just flag you and give you buffs, not sure if this is a do able thing or not but it's only an idea after all.
I think each district I.E. Downtown,Westveiw,International and Richland should all get a set of 5 luggables. Or rather 5 types of luggables per district and make them all different... I've got the idea for this to.
Types of luggables:
1. Mission Luggable: Flags you for pvp and allows you to start a mission that gives out info and xp as well as rep if needed, depending on your orginization. Only difference is that this luggable makes the xp and info from normal missions doubled, rep could be put into it to but the xp and info is good enough I think.
2.Tracer luggable: This luggable is just for people that liked to be tracked and chased... It works like a tracer, when someone comes within 100m of your current location it sends them a message of your coords... It is updated once a minute so it would be rather difficult to track someone or you could just use the luggable detector... Also it of course would give you a buff like, oh idk perhaps speed boost and evade interlock bonus or something...
3. Flag luggable: This item is alittle different from the normal luggable, it could be used for a capture the flag mini game run by the players and of course rules and base locations would be up to the operatives playing, no buffs other then maybe 1 or 2 on the flag luggable. And of course it flags you for pvp.
4.Power enhancement luggable: I believe this luggable should have god like stats on it, nothing to uber powerful but loads of buffs maybe like one of the PB items or something.It flags you of course and gives the holder a huge power increase...Perhaps the buffs could be something along the lines of the assassins mask or maybe the pandoras box shoes.. It should also have a cool effect on you to. Like purple fire or maybe green fire, oohh maybe even white fire and white code eye effect. pwnt!
5. Super rare luggable: This luggable would be very difficult to find because once someone drops it or dies with it in one district it spawns after an hour in another district. The reason it would be so rare is because it would have some awsome effect, something like more memory or perhaps special abilities as well as buffs. Whatever the rare one does though it would have to be something worth looking for... Aswell as holding onto of course. 
Oh and the model for each luggable would be:
Mission luggable would be a cell phone, perhaps a different color one in each district.
Tracer luggable would infact be some small device in your inventroy that could turn invisable so you don't know you have it or something, that way if a noob picks it up, they get mad when they die lol...
Flag luggable would of course be a flag, maybe have the name of the district right on it or something. Also a different color for each district.
The power enhancement luggable would look like an orb or something maybe even a little orb of light.
The rare luggable would have to be golden perhaps a golden gun or something that you can't shoot people with, or maybe it gives you golden code all around your body kinda like that evade combat ability from the hacker tree, what was it called? Makes like a white aura around you but only it would be gold. 
So, if anyone likes these ideas then give me feedback please, and if you have your own little idea to add onto this already great idea, please feel free to add it. Think of anything that you might want as a luggable and put it here, maybe one of the ideas will get a devs attention and it will be put into the game when they have the time to do so of course.
