Is it possible to have local and remote interfaces at the same time?

Hi!

We are using Jonas 4.10.9 and are trying to do clustering. For this purpose we
changed our code from using local interfaces to remote interfaces. But now of
course because of remote interfaces every client action is now MUCH slower. We
still didn't manage to have clustering up and running, but we seriously doubt
that clustering is going to make it up!

a) Do we have to switch to pure remote interfaces for clustering? Is it
possible to have both local and remote interface at the same time? (Like
lookup-methods being smart enough to know if the bean is on local or remote
machine.)

b) Are both interfaces at the same time possible
    1)	in Jonas 4.10.9 ?
    2)	in Jonas 5 with ejb2 container?
    3)	in Jonas 5 with ejb3 container?

c) if clustering goes only with remote interfaces, then what is the benefit of
it if the single user performance drops significantly due to the fact that we
are forced to use remote interfaces?

Thank you, Zoran F.
