    Example Schematic appended...

    I have chosen the PIC port pins randomly, you can use whatever pins suit your design. All Resistors 4K7, all Capacitors 100n. There are three connections on our I2C bus now, SCL and SDA as per usual, and we have added SBS.

    I mean that you CAN do it all with PBC or PBP without difficulty. Use the third SBS (Busy) connection to indicate to the other PICS/Masters that the bus is busy and they should wait.
