[development] hook_form() and multistep

Hi Ryan,

I'm a month and a half late to the party, but I just came up against  
this exact same issue.  I am by no means  a Node API/FAPI 2 superstar  
so I can't say this authoritatively, but as far as I can tell from  
all of the open-ended "Multistep node form" discussion threads  
floating around drupal.org it is not possible to implement a multi- 
step form with hook_form.*    Instead, it seems like people generally  
resort to implementing a #multistep form definition, calling it with  
a drupal_get_form() menu callback, and then using node_save() in  
their form's _submit() handler to store the node in the database.

*I would _love_ to be  totally wrong, chastised, and corrected on  
this point - if anyone has actually accomplished a multistep  
implementation of hook_form() in Drupal 5, a howto would make them an  
instant Drupal folk hero!

Looking forward to FAPI 3,
