Mode two sounds like the "sing-around" method of detecting wireless bugs, which I remember reading about some time ago somewhere (if I can remember where, I'll post - Gordon Liddy's "Will", maybe?) Modes three and four sound like either b___sh__ or a method of defeating particular well-known bug designs. I can't imagine any general way to provide the functionality described. Opinions? Well, IMHO, you could probably duplicate the functionality of modes one and two for $25 worth of parts and an afternoon at the library. As for modes three and four, I'd ask for a demonstration...
