I have been looking at the MSSP module, and phew, looks very messy to start playing with. Anyways I have also some I²C temperature sensors on the MSSP module (or I WILL have, I haven't programmed that bit yet). But as I have understood every device has their own idetifying adress, so I could easily just connect the second PIC on the I²C lines and have it working. Getting data to or from the second PIC would just involve sending a different identification bit, so the second PIC would respond and not the other devices on the I²C bus?
