Separate Client<->Server messages from regular Extension messages
Separate Client<->Server messages from regular Extension messages

IPC has a way to identify the messages by "class", based on the MsgStart
identifier, by using the IPC_MESSAGE_CLASS() macro. This will make
filtering of messages for client<->server interface easier.
