Obviously this is working for you.  A suggestion for increasing the  
surface area of the glued
surface, and possibly thereby the strength, would be to cut matching  
V-shaped kerfs fairly
deeply into the joint-end pieces and then glue that.  Requires some  
precision to make the
cuts; I'm sure there's a tool out there somewhere that does this as  
I've seen the jointing
using this in rafters and other rough construction.
