My main complaint is that that's not user friendly *AT ALL*.

You need to make this useful to mere mortals: go through the 
SDM, categorize interesting looking events, look at how it can 
be expressed via tooling, add a generic event where appropriate, 
provide examples, actually *USE* it to improve the kernel or an 
app and see the workflow as it happens and improve the tooling, 
etc.

Thanks,

	Ingo
