Is it possible to communicate with I²C devices via the GPIOs?
Also, are there any existing drivers or libraries that make this possible from Python?

According to the wiki, I2C is exposed on pins 3 (SDA) and 5 (SCL).
Using from Python on Debian (Untested)
Based on reading this forum post.
Run
sudo apt-get install python-smbus
to install the drivers. At the time of writing, there is a test script here.
Note: Someone needs to test this.
