Well, I'm assuming that it will be published at least in the Group's report, if not on their web site as well, if and when they have one.
Doing a press release brings up the question of who is personally responsible for this, as their contact details will need to go on it. If it's just a submission for the Group, I would suggest that this should be signed by Séan on behalf of ICB, and include his ICB e-mail address. If we turn it into a press release, it'll need a phone number as well, with a real live human prepared to take calls. However, I wouldn't be at all confident about standing over this as a press release right now.
I do believe that a mission statement, or launch document, for a formal group (namewise, at the moment I'm favouring Q-BIC: the Quality Beer in Ireland Campaign) might look something like this. But I think there'd need to be a lot of background work done before such a group can go public.
