On the newsletter I just recieved from Lost Cousins it says:-
IRISH CENSUS - EXCLUSIVE NEWS
A year ago we reported on a ground-breaking collaboration between the 
National Archives of Ireland and Library and Archives Canada to put the 
1901 and 1911 Censuses of Ireland online - and make them available free 
of charge!
At that time it was anticipated that the first data would be online 
before the 
end of 2006 - but nothing has appeared, and there have been no further 
announcements, and so we decided to find out what's happening.
The good news is that the project is still going ahead, and the Dublin 
census data from 1911 will be made available online later this year, 
probably between July and October.
Good news hay!!
