Web crawler that collects comments on social and media websites and lets users analyse and visualise them. It's not very hard to build and provides a great service to businesses releasing PR articles and seeking feedback on them.
Don't know about Ireland, but in the UK you'd need to pay the NLA (newspaper licensing agency) if you want to use news content. And London is crawling (sorry ;) with media monitoring companies.
Couldn't you use something like Google Alerts, but don't tell your customers that, just show the results in a more prettified and "tailored" way to them. ;-)
