For part 4 I'm running through some of the guts of the demo, first up is how the configuration files work and fit together.

Part # 5 runs through the server-side stuff, in particular how file path names are used to implicitly generate topic definitions for RPC registration and subscription.

Part # 6 looks at client-side stuff, this is mostly stuff that's specific to the demo, but it also covers the iFlex autobahn wrapper and the use of mixed-mode macros which are useful for using server-side configuration options in client-side javascript.

And the more we go on the more you appreciate why I could never be a salesman ... ;)
