Ok, let me know how it goes.

Technically.. yes, although, I use the term 'symetric NAT' but the same problem
would probably also happen for port-restricted and address-restricted NATs. But
if you have a full cone NAT (or someone without a NAT) on one end and a symetric
NAT on the other, it's not a problem because you will eventually get
peer-reflexive candidates generate by libnice which will be used to bypass the
symetric NAT.
