Hey Chris,

I already have a ticket open: http://core.trac.wordpress.org/ticket/11160

It does what you want by allowing you to pass an array as the parameter:

     'id' => 'foo'
     'name' => 'My Weird Sidebar name',

I didn't test for this solution yet, but you should be able to pass the same
array to is_active_sidebar(), dynamic_sidebar() and unregister_sidebar() as
you do to register_sidebar().

So, you could set your arrays up for register sidebar and then use those same
arrays for all other sidebar functions.

Assuming $my_sidebars is a long list of sidebars:

foreach ( $my_sidebars as $name => $side_bar ) {

if ( is_active_sidebar( $my_sidebars['categories'] ) ) {
     dynamic_sidebar( $my_sidebars['categories'] );

Unlike now, dynamic_sidebar() will find the id in the array and do the right
