Load balancing Java RMI calls
Can the BigIp load balance Java RMI connections?

So, can anyone confirm whether it is possible or impossible to load balance RMI using Big IP LTM? If the former, could you provide answers to the following questions:
As I understand it, this would require Big IP (iRules) to gain access to the RMI wire protocol internals for retrieving and modifying the server IP sent back (as described above). How is that achieved?
Also, to enable server affinity, Big IP (iRules) would need access to a (potentially application-specific) session identifier from the RMI wire protocol to associate the current session with a particular server instance. How is that achieved?
Given a location-transparent session fail-over mechanism (such as in GlassFish), I guess fail-over in Big IP would be trivial since any server instance from the pool could be used (i.e. would be the same procedure as load balancing the initial request). Is that a correct assumption?
