Well, while the IM bit works in Ireland the voice part doesn't as there is no Irish service number set up yet. Meanwhile the 3 Skype client lacks support for instant messaging unless you are using the dedicated 3 Skypephone. It would be nice if Skype and 3 had worked more in concert on this, specifically if the 3 client supported instant messaging like the Skype client does and/or if the Skype client could be used with the 3 service number for voice for 3 customers.
