I'm attempting to check if the administrator is logged in from an observer. The problem is that while this is easy to do when viewing the admin module, viewing the frontend is another story.
There are several similar questions, but unfortunately none of them provide a working solution for Magento 1.6.2.
I wasn't able to successfully get isLoggedIn() to return true in the admin/session class. I also found out that there is a cookie for both frontend and adminhtml, which may help.
The accepted answer in this related question seems to suggest this may not be possible:
