Hi Taylor -
Good questions, and certainly ones we have at the top of our list. Right now, we’re concentrating hard on fleshing out my.SketchUp’s interface to expose many of the features folks are used to in the desktop application. We have given a lot of thought to the eventual API and importer/exporter approach in my.SketchUp, but we don’t have anything to announce just yet. There is a great deal of technical unknowns still and we don’t want to promise anything we can not deliver.
Regards,
Tyler
