(Radio on master, program and TTL on user). Especially if you use one of the UART's to "outsource" PWM generation, you would have to find a way to share the program and radio ports, unless you forced everyone to use ISP. I think you would be better off using I2C or SPI for the secondary PWM generation.

I did have the pleasure of using Brian Dean's MAVRIC (www.bdmicro.com) on the real time scoring system I developed for Battlecry, and it was a nice change from the Microchip's - but I don't think the Atmega128 provides significantly more than the high-end 8-bit PIC in the RC. (And yes it was overkill for the RTS system, but we had a board laying around).
That is the only thing I haven't been able to work out yet. I have only found 1 real user friendly PWM board.I am sure there are more but I haven't found them yet. I know for FACT that one chip wouldn't beable to do everything. It only has 8 ADCs, 2 USARTs, and a few other things such as IO and such. Now on the other hand the atmega2560 has 4 USARTs
