MAC address change, good idea or not?

Is it a simple and risk free process to change the MAC in MX5?
I am looking to create a wifi hotspot for a Nintendo 3DS for streetpass.
So to be clear, I am looking to change the address of the wifi adapter.

@dazers all you need is root and Busybox, just like Terminal Emulator, then run these commands:
su

  • This will give you superuser permissions.
    busybox iplink show eth0
  • This will return your current MAC.
    busybox ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX
  • Change XX:XX:XX:XX:XX:XX to the MAC of your liking.
