Why Phantom

Phantom is the "ghost who walks" - an entity whose presence can be felt (in a good way) but its existence need not be acknowledged. The Service Proxies fit this analogy well and therefore earned the moniker "Phantom". Motivation for creating Phantom and design overview is described in this Proxies for resilience and fault tolerance in SOA blog post.
