Trustin/Mircea,

What exactly do you guys mean by 'native'? Something like what HornetQ guys did? Or your talking more about adapting an existing cache store impl library to suit our type of ops? 

I suppose you'd be targeting the local cache store space and not the shared one, correct?

I do have some doubts on whether spending time implementing another cache store impl would be really that useful.

When I was in Berlin, rather than implementing another X cache store due to performance, I heard users asking more about whether they could have their existing databases be read by Infinispan cache stores, to avoid having multiple databases, one for a shared JDBC cache store and one for their JPA or similar ORM databases. Granted that this could be done with a Hibernate based cache store but then again you could be wondering whether they should not just use Hibernate directly with a 2LC.
