After a few minutes fiddling it seems you make "processors" which can do things like file input/output and data manipulation, chain them by dragging a connector; outputs can be things like SFTP. Closest thing I've used to this would be YahooPipes but this is self-hosted and so can access local files and such - seems powerful but I [as a non-coder] wonder if it wouldn't just be quicker to knock up a bit of python script for the sorts of things I imagine doing with this; that's probably a lot to do with limitations in my knowledge (of both).
Some good demos/examples one can mess with would be great.
