This is pretty neat, but it seems like an advanced version of Google Docs Spreadsheets. I wonder if they'll roll these features into that. The OSS project is nice for confidential data, but I think a lot of people would use a hosted version. Anyone going to set one up?

I literally just did the same exercise as demonstrated in the second video, parsing a Wiki document (the list of world religions) from Wikipedia. But it took about 30 lines of PHP.

Maybe they'll add the ability to import a web page as a data source, and export the script that does the transformations as a python script?

Okay. I'm rambling...
