Just a couple of questions to take with a grain of salt since they come 
from a man who knows just enough to be dangerous ;)  :

In the case that you go for and event stack :
   -isn't the event system being recoded by Lukep right now ? If so how 
much of your efforts would soon become obsolete if any ?
   -replaying the events, without any undo stack, can take a loog time 
can't it ? Much longer than a video sequence.

In the case you go for OpenGL recording :
   -how much overhead will this add to Blender ? Won't it slow down to a 
crawl on most machines ?
 A possible solution to this would be to suspend the recording while 
Blender is working hard and blocking the user from accessing the UI anyway.

Now can you tell me what is your motivation ?
Until now I just couldn't shake off the impression that yours is a 
solution in quest for a problem.
I make a lot of tutorial for the company where I work, some are about 
Blender, and I use Camstudio with its lossless codec (less overhead at 
recording time) with litterally perfect ease.
Many other solutions exist so why ?

If nothing else your answers will make my reading this thread a lot more 

Congrats for the new baby :)
