Common Travel Area to go?

It may have survived Irish secession and the second World War but it seems the Common Travel Area may soon be over. The UK intends to introduce an e-border scheme for all air and sea passengers in 2009. This would mean Irish citizens would need to be in possession of a passport when entering the UK by those means. The UK is not expected to apply the scheme to the land border and it appears the Irish government may introduce a similar e-border scheme as well.
