> The motivation for this is that in constructing a complex  interface the number of varfiables and functions may get quite large and further,  these variables may also need to be accessed in another function that is nested  more deeply . For example, function foo may call other functions which in  turn call other functions ... until finally the bottom function may need to  access say the variable - x1. Having to  repeatedly pass the entire or selected parts of  the variable space can get unwieldy and impact on the final code's  readability. Thanks.
You can splice in the contents of the variable args into Module or 
DynamicModule by using Evaluate:

args={aaa,bbb,ccc,ddd};

Module[Evaluate[args], ddd]

ddd$1987
