Because the remote receiver wouldn't fit inside their fan's canopy? I told them that most canopies are the same size including the replacements, which is true. However I just spotted this:

Which is a receiver that mounts OUTSIDE the canopy.

And now I can't find the original post!

I have a Casablanca ceiling fan, mouted in our stairway, on a three way switch. We want to add a light kit (no problem), and want to be able to operate the light and fan from the three way switch. Lutron makes a nice switch (MA-LFQ3), but the canopy controller is a bit to big. It measures 4"x2"x1". We only have 4". We only have 4"x5/8" room in the canopy. This is hanging from a pancake electrical box, so there is no room there either. Question: does anyone make a smaller controller unit that would work' or does anyone have an other idea how to hook this up? Thanks Jim

What model Casablanca fan is it? How is it currently controlled?
