Interesting idea. 

I didn't think it was to hard if you had user that was fiddling with your 
source to just have him generate his own keys and while I just compile my keys 
into my official binary builds but I guess for scripting based clients, this 
makes sense. I guess you get the attribution and client tracking on the Twitter 
side as well. 

Sometimes though this is not ideal, like a wordpress twitter plugin I use. I 
forced it to use my own keys because I want it to say "" in the 
attribution link and not "UberWordPressTwitterPlugin" or whatever. 

If you can make it where the user can optionally edit the source attribution 
tag and link when they set it up the clone, then I would probably direct my 
users to use this approach over manually creating their own original consumer 
and secret.
