Looks like a cool project... but I hope the plan to open source their library to export Scikit-Learn classifiers to PMML! This would be a great way for them to give back to the open source community.
We'd love to do this. As you can imagine, however, it's a very time consuming task, and there are a lot of competing priorities (including other projects we've open sourced) and we therefore can't make any guarantees about if/when we'll be able to do it.
