Paul, The reasons I think the drive from the rotor won't work.
The balance problem alone would be one reason I would avoid it! 
This thing might BE balanceable, but would weigh a ton once itwas done. 
Sealing the rotor with the shaft attached
is another. The lubrication trouble you would have is another. 
There are ways that this thing could be made to run for a short time. 

I am not trying to be insulting here either. To Vance; I know that power 
can be extracted where ever you can grab the engine, and I am aware of the camshaft drive
you (Vance) mentioned. The fact that you could get a 3:1
speed reduction would be great and I DON'T disagree that
 that portion of the drawing would be good. I must say however 
that I do not like cantilevered loads especially on fast moving 
engine parts. I would be very interested
in what the load and then reverse load on the eccentric shaft 
when the second rotor drives out through the e-shaft would do. 

I also think that in the metal this monster would try to rock the 
rotor and ride up and off the stationary gear. This would cause a 
great deal of force towards the "open" side ofthe rotor. The same problem 
with the cantilevered load on the e shaft! Rotors are heavy, and not having 
a bearing on the drive end seams to beg for disaster all by itself. I can't 
see any way to get around that problem without having the fifth dimensional 
unobtainum drive shaft that can orbit through
the material of the missing side plate. Another big problem in a 
single sided system. 

To control oil in the stub e-shaft you would have to have the drive 
side closed. The closed side would make a piston for the oil pressure 
to work against, again trying to force the rotor out to the drive side.

Don't get me wrong, I LIKE unusual configurations.
Something that attracted me to the rotary in the first place.
I even looked into building a Burt-McCulloum single sleeve engine. 
When looking at the drawing again I think it's an idea that while you 
might be able to make such a thing run, I think you would lose every bit 
of the power to weight advantage that makes the rotary attractive in the 
first place.  I even tried to come up with a design of my own to do the same 
thing. 

But Mr Gravity, (aka Paul) busted me on several items. Very correctly I must add.
