[Catalyst] Invoke *complete* subrequests in Catalyst?

[Nate Wiger]

Is there a way to invoke a complete subrequest, with a complete request 
cycle, in Catalyst? I've tried the Plugin::SubRequest and it's a step in 
the right direction, but what I need is something that allows complete 
prepare()/finalize() functionality.

I'm building an AJAX app with FormBuilder, and want to use it to embed 
multiple forms in a page (each of which would be linked to a different 
action and submitted using JQuery). I've found I can do this, but I've 
had to make changes to the FB plugin so that it only instantiates an 
object on a call to $c->form, and doesn't use prepare() to do so. This 
then requires a bit of internal magic to work both normally and in 
subrequest mode.

Other ideas?
