Look at the three 2s next to each other in the middle of the puzzle. Your middle 2 has 3 lines around it, which renders the solution you provided invalid.

I enjoyed the puzzle (11 x 11 4 March 2010) but think your solver is wrong. A bit hard but not insanely difficult. I found it whilst looking for takegaki logic rules.
