Has anyone seen or know where I can get some of these?

A small relay, that can fit into a j-box, has NO/NC contacts with a 120v coil, and looks remarkably simular to a smoke detector/fire alarm accessory relay. (Has heat shrink case) But for lighting control etc.

Look kinda like this...

I have seen them, have been looking for some, and half tepmted to go down to a building that I know has them to find out who makes them.

We occasionally use a similar relay. The local refrigeration supply houses sell them, the ones we use are called a RIB, relay in a box. They have NO and NC contacts and work on various voltages. Real handy sometimes.

RIB is very simulat, but looking for one that can be placed indide any box. For instance, the ones in the building I mentioned control 6 floors of common lighting for off hours. It shuts off power to about 36 switch boxes by running a single circuit through all of the boxes. Each had very low draw, but handled ~20A switching each. (I believe were motor rated too, and also multi voltage coils.) They were about the size of 4 quarters in a stack, really small, and fit inside each switch location. So they were really unobtrusive. I swear, I'm going to have to sneak back in there and open a box and steal one. I remember seeing them and saying, "Man those could be handy..." Now I believe I have found a really good use for them.... Switched receptacles, flouresant lighting and anything else controlled by Grafic Eye or other simular lighting controls.

What you describe sounds rather like the GE RR-7 and RR-9 lighting relays.

No... Thats it, the next time I'm there for a service call, I'm getting one, or at least finding out who makes them.

Wonder what this does to box fill, strictly in a theoretical sort of way.

Sounds like one of those great little problem solvers to keep on the shelf. Please let us know when you find out who makes them.
