[Design] open-source RDF-based peer-to-peer PIM

[Aaron Swartz]

It's wonderful to see so many excellent people collecting around such 
an excellent project! Can't wait to help make this happen.

You might be interested in the Haystack project, which is doing 
something very similar.
"""
The Haystack project makes use of Semantic Web RDF technology to permit 
maximum flexibility in describing information. On top of this we have 
created a user interface paradigm capable of displaying various kinds 
of information in many forms. We provide a powerful infrastructure for 
incorporating machine learning algorithms that implement 
personalization and per user adaptation. Our framework also facilitates 
and fosters collaboration between Haystack users.

As you can see, they're also doing an RDF-backed peer-to-peer 
open-source PIM and hopefully you could share some code.

All the best,
