Exactly. The idea was that 2LC users should need to configure as little as possible of Infinispan, hence focusing on configuration options within Hibernate settings. In this case, the transaction manager set up for Hibernate can be detected by the 2LC and plug Infinispan with it.

The way I did it is create a HibernateTransactionManagerLookup class that implements org.infinispan.transaction.lookup.TransactionManagerLookup and looks up the transaction manager with Settings.getTransactionManagerLookup().getTransactionManager(properties)

I don't think you should depend on the 2LC module. Instead, maybe we should have an infinispan-int/ or infinispan-core/ module for shared Infinispan stuff that several Hibernate modules might benefit from?
