Pantoto Communities project is over a decade old now.
It is an open source project and our initial code base, which was developed in Java, served us for 4-5 years before becoming a legacy system! Pantoto.com is a frozen indicator of how it worked and what it did.
Now, its been developed using Python and Mongo. The api is ready and available to be tested and a web.py Web interface is almost ready.
Earlier version has decent documentation of the Pantoto idea http://code.google.com/p/pantoto-mango/
