Hi, Denis!

You have my answers inline.

Not really, it depends on the scenario you want to achieve. For example, 
in a federated platform, you don't need to have L2 channel, because each 
server will use it's own IP. However, if you want to have IP HA, you'll 
need to use heartbeat or keepalived to share the IP between instances, 
and that might require L2. But again, the clusterer module does not have 
any extra requirements, but plain IP connectivity between the nodes in 
the cluster.

This can be achieived using a HA setup + dialog replication whithin the 
HA cluster.

This will again need to be implemented using a VIP or something, so that 
rtpproxy can send the timeout command to the node in charge of the dialog.

There are a lot of modules that have not yet been ported to a clusterer 
setup, some due to lack of time, or perhaps because we did not see a 
useful scenarios for them. If you do have examples of scenarios where 
that would be useful (I agree fraud_detection might be one of them), 
please open feature requests on our tracker, so we (or anyone from the 
community) can take them into account for development.
