It's probaly equal or at least very simliar. Can struts "widgets" be nested
like TS objects?

It's already implemented it that way. I should say, there wasn't much to
implement. The interface to the subcontrollers is in fact the same as that
to the main controller. Every main controller can be used as a sub and vice
vesa.

$returnString = main($input, $configurations, $context=NULL,
$parameters=NULL);

Once context and parameters have been build, they can be given to the sub,
so there is no need to build them a second time.

It could be used for example to very naturally implement FE forms in IRRE
style.

Yes, the kickstarter can probably offer more Ruby on Rails like feature
using subcontrollers. I have to read about RoR, what makes it that special
amoung other MVC frameworks.
