FYI -- we moved Virgil to Github to make it easier for people to contribute.
Also, we created an organization profile (hmsonline) to house all of our storm/cassandra related work.
Under that profile, we'll be releasing cassandra-triggers.
It is an AOP-based trigger solution that provides a simple trigger/event-log that can be used for data replication and indexing reacting to column family mutations.
