Missing something. :-)

The functionality is mostly already present in emacs.  The function 
dired-find-alternate-file (normally assigned to the 'a' key in dired-
mode) replaces the current buffer (the dired buffer) with the 
file/directory that the cursor is on.  When the function exits the 
dired buffer containing the original directory has been killed and 
the active buffer contains the file/directory that was opened.  

Going down in the directory tree is intuitive.  Going up the 
directory tree requires that the cursor be on the '..' entry in the 
dired buffer.

If you are used to using the '^' to navigate up the directory tree 
then you will either need to retrain yourself or will need to do some 
elisp programing to attach the functionality to the '^' key.  I 
looked at the function dired-up-directory (in dired.el) which is 
associated with the '^' key, it does not look like it would be too 
difficult to create your own function based on it and assign it to 
the '^' key in dired mode.

Good luck,
