Tim Beermann posted in my comments that:
Shape2Earth can now be downloaded and tested at http://interactiveearth.blogspot.com/.
I have not had much time to implement a lot of the features I would like .. but those will come with time.
For those who have not been following Shape2Earth Beta 2 news, you can get up to speed on the enhancements over on Tim’s blog. Good news as GIS professionals are really starting to take a liking to Google Earth and making it part of their workflows.
Ah, but Google Earth’s pesky EULA gets in the way.
