The scoring diagram leaves little doubt about that. The second place goes to team h4ck!nb3rg, Janet Reno Redemption Fund$ made the third place. Congratulations! Some more diagrams are available, as well as the vulnimage, testscripts and all reported advisories.
We had 34 teams of which 22 managed to find their way into the CTF VPN. Some of them (including the winner) were local teams, playing directly from the congress area. More details will be published in a few days in the congress wiki
We’ve also got a photo of our VPN router, which we bought and assembled one day before the contest ;-). Thanks to the NOC team (arien, panther_1, zaphodb), who let us put this thing into their server room. Since our hardware got lost on the way to berlin, they also hosted some vulnimages for us. Thanks for that, the CTF team really appreciated your help!

Is the vulnerable image available somewhere for educational purposes?
Yes, it will be. Will still take some days, though. Watch the wiki page or the IRC channel. Notices will also be sent to participating teams via email.
