Correct. Right now the only thing you can do is use infinispan and jgroups directly.
However the ininispan in beta3 has issues running in a modular env (there is a patch for
this in 5cr1). The most recent checkout works around the problem.

Actually, no. It turns out that the command-line argument handling in Beta 3, requires
this syntax:
./standalone.sh -server-config clustering-standalone.xml
The "equal" sign does not work, but a space does. I believe Jason hinted that
he might fix this, so it may change in Beta 4.

So far, nothing that I can tell. I just had a e-mail conversation with Remy on what I
thought might be an issue with HTTP session replication, but he says its not in there
yet.
Also, while there is a configuration for Hibernate 2LC, that also is not completely
implemented.
My guess is that none of what's configured is actually complete.
