We are also facing the same problem,
Our application is a normal ERP application with lots of module, all the
user do not use all the module,
thus User A who uses only Module A has to download all the 15 module, now
till now its not a big issue(its not even an issue as our output js is still
very small ) but still was thinking why is it so complex kind of next to
impossibel for us to bind js file on the runtime .. i mean USER A access
module A, and moment he click's on Module B and RPC connection download's
the required js file.
