Call Customer Name in Header

[killertofu]

I am trying to mimic a "Hi, [name]" at the top of my page. I'll explain...

When a guest comes to my site, I would like it to say:
"Hi, Guest. Please register or login."
The "register or login" linked to the login/registration page.

Then when someone logs in, I would like it to change to:
"Hi, [First Name]."

I suck at php, but this is what I constructed so far. Don't laugh:

Hi,

<?php if ($_SESSION['customer_id']) { ?>
    <?php echo $cust->fields['customers_firstname']; ?>
    <li><a href="<?php echo zen_href_link(FILENAME_LOGOFF, '', 'SSL'); ?>"><?php echo HEADER_TITLE_LOGOFF; ?></a></li>
    <li><a href="<?php echo zen_href_link(FILENAME_ACCOUNT, '', 'SSL'); ?>"><?php echo HEADER_TITLE_MY_ACCOUNT; ?></a></li>
<?php
      } else {
        if (STORE_STATUS == '0') {
?>
    <li><a href="<?php echo zen_href_link(FILENAME_LOGIN, '', 'SSL'); ?>"><?php echo HEADER_TITLE_LOGIN; ?></a></li>
<?php } } ?>

Is this impossible to do?

On a brand new install, it already does that on the home page.
If I recall correctly, enabling/disabling that feature can be done in the admin under Customer Details configuration.

If you wanted to relocate it to some other place on the site, you'd have to go into the templates and find the existing code, and move it to the appropriate new place.

I've seen it moved to a sidebar on some sites, for example. I imagine they just copied/moved the code from one template piece to another.
