Genius from company A chooses public IP block A. Genius from company B chooses public IP block A.
Genius collision detected... That's pretty nasty. However this should be able to mitigate some of the ugly scenarios brought up in this thread:

Company A uses public IP block A internally. Company B uses public IP block B internally. Company A and B later merge, and connect their networks. No conflict, no renumbering needed (at least not right away).
Compare this with company A and B both using overlapping part of for instance 192.168.0.0/16, and then merging. Conflict ensues, renumbering or NATs required in order to connect the networks.
