A normal SecUnit (you know, one that still had its governor module, less anxious than me but probably more depressed) could do this part, but would be restricted to the canned responses available in the combat stealth module. A drone might be able to recognize those responses as coming from another combat unit and not a human. I didn’t have the combat stealth module anyway (I had never been upgraded with it, probably due to RaviHyral and the whole "killing all the clients" thing, go figure), so I used snippets of dialog from my media storage, extracted and processed to eliminate background noise and music and to remove any identifying code underlying the audio. I sent my prerecorded "Are you—can’t find—where—ship—" artistically obscured with static.
