you're welcome L, read this from Matt Cutts,
Solved: another common site review problem, he's a google SPAM engineer. He states that spiders have problems indexing drop downboxes.
So you could have a drop down box in the top right hand corner to get people to select their country, if it's different to Ireland.
btw. you can have sub-sub domains like
product1.us.customerminds.com
product2.us.customerminds.com
product1.ie.customerminds.com
product2.ie.customerminds.com
but that might start to get confusing
you could get penalized for
SEO if you have three directories with 99% of the same content, although you could use the "noindex" attribute to keep them out of the index.
