All the usual hotels and hostels exist around the big touristy areas and towns, but are still quite expensive and would not be a long term solution. Camping is by far the most reliable for of long term sleeping arrangement as tucked away, empty fields can be found just minutes outside even the biggest towns. The farmers would probably appreciate your asking if you could stay but for the most part they probably wouldn't even care. Just try not to go into fields with crops or livestock and never light a fire that would be visible from a road or house. Forest fires aren't really an issue in Ireland either as it's usually so very wet. You could also try www.couchsurfing.org for accommodation if you're interested in meeting local people. Most showers of rain in Ireland pass quickly but if you're unlucky enough to experience the weeks of drizzle and rain which can sometimes plague the country at any time of year you might need to cash out for a B&B to get a good nights sleep or to get a chance to dry out.
