Right right, exactly, but how to I get the writer?
How do I get the writer from the parent velocity template such that I can
pass it to the child templates and have there output slip right into the
output of the parent?

If all the components uses Velocity to render the content, you must be using
Template#merge or Velocity(Engine)#mergeTemplate or
Velocity(Engine)#evaluate in each of your components, correct? If so, you
can just put the Writer in the Context before rendering.
context.put("writer", writer)
And in the template,
$component.render($writer)
