Is there a decent alternative to Yahoo Pipes?
(This question has been asked several times...n For example:Yahoo Pipes clone script?Alternatives to Yahoo Pipes)
Pipe2py is a compiler script that will generate a Python equivalent of a Yahoo Pipe given the URL of the pipe:

(Note that not all Pipes blocks have yet been implemented.)
A "hosted" version of Pipe2Py is also available on Google App Engine: http://pipes-engine.appspot.com/
