Do you know about any documentation for these 433 MHz proprietary
protocols? What about using 802.15.4 or ZigBee?
I want to use Freescale MC13233C [1] in my indoor/outdoor temperature
and humidity monitoring project. Please tell me, if you know about
cheaper 802.15.4/ZigBee modul or about any free samples from
semiconductor manufacturers.

Apart from I2C, perhaps 433MHz equipment is an option? I have been
looking into combining that with my Freerunner (or Phoenux) for home
automation.
There are those weather stations that come quite cheap as long as you
don't need USB (or other generally available) connection. Many of them
use the same chips and for Arduino there's a library [1] available to
read temp and humidity.
Then you still have to interface from Arduino to your Freerunner of
course (and you'd need an Arduino).
