Has anyone ever written inline code for https://playground.arduino.cc/Main/SoftwareI2CLibrary/ or something similar?

I have never seen an i2c device unable to change the address.
If you still need it then look at an i2c expander

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA/SCL pins!" Are you out of...
Would like to get multiple nanos to network without extra hardware and without eating up all the memory. They would be using their i2c buses as master so can't just set the extra nanos as slaves. Softserial is very resource intense. Trying to leave the hard serials for debugging. This seems like a simple option rather than writing my own protocol.
