Import Basecamp tasks to Omnifocus? Script?

I’m using Basecamp2, so Spootnik unfortunately isn’t an option. But I’d like to know if there’s a script or some way to import Basecamp tasks assigned to me from Omnifocus. I don’t necessarily care about them then showing up as completed in Basecamp (synching back), but I’d like to have all my to-dos in one place.

Anyone got any tips?
