I'm also interesting in your project and will be glad to follow you on twitter if I can.
We have already built something similar and were planning to open source it. It will be available under http://www.elasticinbox.com/.
We haven't followed exactly IBM's paper, we believe our Cassandra model design is more robust. It's written in Java and provides LMTP and REST interfaces. ElasticInbox also stores original messages outside of the Cassandra, in the blob store.
Let me know if you are interested, I will need some time to do cleanup.

If anyone can point me to researches/articles that would nudge me in the right direction i'd be tremendously thankful!
