Obviously not -- but also obviously, w/o the password, no one else can 
open it either.

You need the password to open it. Without the password, there isn't 
any realistic way to open it. It may go without saying, but that's 
the purpose of password-protecting a file -- that it can't be opened 
w/o the password.




There is an OOo macro available that takes a list of possible passwords and will 
attempt to open the file. If your password was a random sequence of letters 
and/or numbers, it won't work.

Not quite true. Source code at
http://www.oooforum.org/forum/viewtopic.phtml?t=23014highlight=password+cracker

125 passwords checked per second.
Number of possible passwords is k^n.
  n = number of characters used in the password;
  k = number of glyphs that can be used;

Macro is at 
http://sourceforge.net/project/showfiles.php?group_id=87718package_id=173080

You might be waiting a very long time.

The break even point for an OOo password recovery service is around
US$10^9 per document.
