I think that's an understatement. It's a massive achievement by Iain, and he did 
it pretty much all on his own. Very few developers have both the technical chops 
and dogged persistence to pull something like this off. It's a career-making 
accomplishment, and all Iain ever needs to put on his resume!

We're all enormously lucky to have Iain on our team!

Please join me in hefting a pint to Iain!
