Lighting, Light Fixtures, Ceiling and Exhaust Fans - Combo fan/light control w/3way for light

I'm installing a ceiling fan and would like to have a combination fan/light switch controller with dimmers. No big deal right?
However, I need to have the light on a 3 way so I can turn the light on and off from 2 entranceways in the room. I've called a few lighting suppliers and they cannot find anything like this.

I cannot break up the combination because I don't have anymore room for another switch.

Any ideas?

Thanks...

I'd use regular three way light switches in the walls and then use a wireless remote to control the settings on the fan and for dimming. If you want to do it from both locations, you can buy a second remote but you'll probably never use it.
