user4731: Is it possible to use more than 1 device that needs to use SDA for I2C with a mini?
Would you use a different analogue pin with a 10k pull up resistor and tie all of the devices to the SCL?

Is it possible to use more than 1 device that needs to use SDA for I2C with a mini?

Yes, provided they have unique I2C addresses.

Would you use a different analogue pin with a 10k pull up resistor and tie all of the devices to the SCL?

No. All of the devices must be tied to both SDA and SCL. You may need a smaller resistor depending on how many devices there are; see NXP document UM10204 for details.
