[Sugar-devel] Device's Universally Unique Identifier

[Gonzalo Odiard]

If Sugar is used in a XO, there are a unique id and you can get it as here:

https://github.com/sugarlabs/sugar/blob/master/extensions/cpsection/aboutcomputer/model.py#L52

Maybe in the case of non xos, you can use the mac address of the active
network interface?
