1-wire (Dallas/Maxim) and PWM

I want to make a chain of 20 modules for PWM dimming of 12-volt LED white strips (1 meter each). Since the controller is at a distance of 30-40 m, it is preferable to use a 1-Wire bus. The master device will be an Arduino.
Are there any specialized ICs for this? I'm found only Maxim DS2405/06 ICs, they can work for PWM or not (slow frequency)?
Or may be is it easier to do on each module with Attiny85 & MOSFET?

I'm found this project: http://littlewire.cc/ - low cost & small MCU Attiny85 and library for 1-Wire/I2C/PWM etc.
I will try this and be back :wink:
