No, as far as I know no one is working on transaction support in Cassandra. Transactions are orthogonal to the design of Cassandra[1][2], although a system could be designed incorporating Cassandra and other elements a la Google's MegaStore[3] to support transactions. Google uses Paxos, one might be able to use Zookeeper[4] to design such a system, but it would be a daunting task.
