When this is discussed, one thing that would be nice to think about  
is whether this could be leveraged to fix the problem with input  
filters.  Specifically, that input filters don't get any context  
(such as a node object), so the most useful ones have to implement  
themselves via hook_nodeapi() (cf inline.module).

If drupal_render is going to be called on nodes to render them, we  
could do something like:

$node['content']['my_field'] = array(
   '#value' => $node['my_module']['my_data'],
   '#filter' => $node['my_module']['filter'],
);

Which when rendered would generate call the input filters, but be  
able to give them the context of the node.

We could even support something like

$node['content']['my_field'] = array(
   '#value' => 'This is my @interesting text',
   '#keys' => array('@interesting' => '<b>special</b>'),
   '#filter' => get_filter('default'),
);

Or, if you wanted to be even more interesting,

$node['content']['my_field'] = array(
   'first_part' => array(
     '#value' => 'This is, after all, ',
     '#filter' => 1,
   ),
   'middle_part' => array(
     '#value' => '<blink>not</blink>',
     '#filter' => 0,
   ),
   'end_part' => array(
     '#value' => ' rocket science; is it?',
     '#filter' => get_filter('php'),
   ),
);

If done right, this could entirely eliminate the need to call  
check_plain and check_markup as well...

But the key point is that if we use '#filter', we could get a context  
object to input filters, and that would make many input filters  
easier to create.
