/**

Contains information (of interest to the TSP) about a client of RemCon.

Includes the client's process ID and the client's current send message 

(RMessage2) which is triggering a request (AddressOutgoingCommand or 

PermitOutgoingCommand) on the TSP. Via the RMessage2, the TSP can access the 

client's secure ID and also do capability checks on the client.

The process ID is also used by the server to police creation of target 

sessions (only 1 is allowed per client process).
