Redhat SOA Stack Usage

OCS desires market research to identify the market penetration and usage of the Redhat SOA Platform. Specifically, the Redhat SOA platform has many components (listed below for reference). Which are actually used and how often are they used. For example, do new SOA applications using JBoss remoting? Perhaps there are just a few permutations. OCS is developing a monitoring product and needs to know the typical architecture of a Redhat SOA platform application, i.e., which of these components will typically be part of it.
