portfolio

I am using Drupal's blog module to provide a lightweight electronic portfolio tool to students and teachers. I could use your feedback on the approach I've taken using content_access and hook_form_alter. Is this the best/safest way to do this? I still feel like a relative newbie to making these modifications.

For a fuller example of the reason for using blog as a portfolio, please see http://www.kassblog.com/item/1030

I added a checkbox field to the blog content type.
