Unless I am missing something here IPMP only increases throughput on the
outbound side of the server. Media servers are typically bringing data in from
the network. 

Excerpt from docs.sun.com:

Outbound Load Spreading
With IPMP configured, outbound network packets are spread across multiple NICs
without affecting the ordering of packets. This process is known as load
spreading. As a result of load spreading, higher throughput is achieved. Load
spreading occurs only when the network traffic is flowing to multiple
destinations that use multiple connections.
