Convert *.PST Files to Something Else (LDAP...)

Hi, Is there any way using PHP (or any thing else, preferably PHP) to convert a MS Outlook *.PST file to another file that would be usable by PHP, using only PHP scripts, or even a CGI? I am working on an open-source project called falconmail that needs to be able to import all sorts of mail files from people's old programs.
