I have not seen the dromedary anywhere else.

As far as disrupting trade lanes, I believe the story is that the Hackers stole some kind of tech. that is involved in the trade lanes from Agiera, and now they know how to disrupt them by some method other than simply blasting the rings.

The devs missed a great opportunity here.

They should only allow a player to hack trade lanes after he/she has obtained the necessary technology from the Lane Hackers.

what i dont understand is why you can use trade lanes and jump gates owned by hostile factions, they shoot at you, so they seem to know who you are, but they dont reject your use of them. that would have been another tech you could get, something to override the lanes/gates.

and one more thing to add

if u can use pirate's trade lanes, why not hostile navy or police trade lanes?

The trade lanes are built by corporations and are run by the corporation branch/local police/militia. In theory, the various pirate factions who lane hack would either brought the technology from the Lane Hackers themselves or acquired it through their own sources.

By allowing the player to disrupt the trade lanes with a simple laser blast, it just doesn't fit into the backstory. Moreover, that's vandalism/sabotage of government property, shouldn't the police or military be compelled to act in such instances? From what i have seen, the self defense mechanism of the trade lanes are nothing but a minor distraction to the lane hacking pirates.
