my idea is to separate the callback registration out of the menu system,
and make all the callbacks we can address (ie: nodeapi/load) be  
stacked onto
the callbacks via the forms api callback format. Hooks are just  
automatic callbacks.

ie:
$callbacks['nodeapi/load']['my_function_here'] = array('args', 'here');

Also, keep in mind these are flat lists. not nested arrays like forms  
api.
They don't need to be processed into the tree like the menu array does.
