Custom Menu on Profile Page

I would like to customize the tabbed menu that displays on the user profile page (View Edit Contact etc..)
I would like to display these items on a block that will display on the side of user pages.

I've been looking through forums and docs (http://drupal.org/node/35728) for the best way to do this and haven't found a solution.

I think I need to test whether a user can edit an item, (i.e. can edit account settings) and if they can edit that item, then display the link.

I found this: http://drupal.org/node/328073

which is pretty close to what i am looking to do, except that it test if a user is viewing their own page.

Also, I am using the Content Profile module, which I would also like to display it's [edit] link on the block as well.

Thanks for any help or direction.
