Dear @Juan_Manuel_Perez_Lostao and @David_Clegg,
I would like to use an analogy
When you go out on a trip with your family you can use a family car. 
When you go out on a trip with the football team you need at least a bus 
for everybody to join the party
As @Paul_Danyliuk, clearly stated, “everything has it’s limitation” and he has proven that there are many ways to deal with it at a certain extend.
I am sure that scalability is high on the agenda of Coda and of course it’s always good to emphasis your concerns
