Diverse in Unity

So, because the Irish voters were stupid enough to dump the Lisbon treaty, it's time to talk about the alternatives to the present way of changing the founding treaties.
One of the possible solutions to the apparent impasse, when countries like Britain, Ireland or Denmark refuse further integration and rather want the EU to remain non-political intergovernmental organization, is to form a two-speed Europe.
What would it mean? Well, first the EU would be 'divided' into two parts. The "core EU" would go on with integration as far as it would please, perhaps even to forming a federation. Only countries ready for closer integration would be a part of this core. The remaining members would stay in the EU, but they'd abstain from any further integration, while enjoying the benefits of the membership in its present form.
I used to be against it for many reasons, such as the legal mess which would ensue if some parts of the bloc had different rules, the obvious end to the unified approach etc. Now I am starting to believe that these disadvantages don't outweigh the advantages.
It is clear that if we want to move forward, some of us anyway, we simply can't wait for the rest. The pack is only as fast as its slowest member, which means that if the slowest member is not moving at all, we all are moving nowhere.
EU, in my opinion, simply can't afford to stagnate, that would doom the project. EU can't enlarge without institutional changes which allow it to cope with the new situation.
Moreover, two-speed Europe would once again ignite competition in Europe, and competition has brought us where we are. It would soon become clear what is better - to integrate more, or to integrate less.
So, what's your opinion? Vote in the poll.
EDIT: I made a map. I am not sure about the undecided countries, so posters from these countries should feel free to explain their country's standing:
