That's a good article. I've read quite a few, but didn't really get why a Greek default was such a big deal until I read this explanation. It's sounds like the ECB is in a pretty fragile state and any default would challenge the value of the Euro. I don't see Greek getting out of this without defaulting, as they've proven they're not keen to embrace austerity, and in my opinion, the European Union is just throwing good money after bad at them.
