Irish DNA Testing?

Back in May, the Irish Times carried a short article, Discover Your Genetic Ancestors.  It was about “Ireland’s DNA” that is a new service similar to the one that has some popularity in Scotland called "Scotland's DNA."  In Scotland about 1,000 people have paid to have their DNA tested (as about 250 euros.)  For Scotland Norse raiders would be expected, but for about 1% there is a Berber line.
There are lots of tales of who and where the Irish came from, maybe there will be some answers and a few surprises.
