Ted got back to me with what he could do this afternoon. Here's what he had to say:
Alright, so I've been doing some steady work, and I think I've got something figured out. What I've done, basically, is set up a private wireless channel - similar to a police band or CB radio, if you're familiar with those. I put the prototypes in retractable ballpoint pens. You press down the thingy that would make the pen work, and then you get your transmitter activated, and whatever you say will go out to whoever else has one set to your channel. Magic's in it, so you don't need magical power of your own to operate it. Fits in a pocket, so carrying it at all times wouldn't be any trial. And I'm really quite proud of the volume control - Remus, thanks for finding me the books to get that working right.
It's not perfect. I don't have a way to make it completely private, and of course anyone who's around when you use it would hear it. However, if you're in an emergency situation, that's not necessarily going to be a problem anyway. Still, it would be a good idea to set up some code phrases so you can say things without saying them, dig? But anyway, you and Nick and I can test them out when you two are running your shift tonight. There's also the fact that if you break the casing, it's going to be useless. We may want to see about some protective charms on the device itself - so far everything I've attempted ends up screwing up the transmission, but we can keep trying.
