We were looking for the same option, so we developped it.
The goals are :
- store file on disk,
- reuse some files instead of storing them every time,
- create a CF which could propose a list of preloaded files to "attach",
- be able to populate this CF directly from the filesystem (through a 
script)
- etc.

Plus, we wanted to keep as much as possible the way RT was managing files.

The code relies in :
- a sql file, needed to store the references to the filesystem 
(attachments was not relevant due to transactionid and to keep most of 
RT's code)
- Document.pm , a class inheriting from Record,
- some minor changes to Attachment.pm and CustomField.pm,
- some minor changes to share/html/Ticket/Attachment/dhandler
- some minor changes to share/html/Download/CustomFieldValue/dhandler

The db used is postgresql, but I think it would be easy to port to mysql.

Let me know if you are interested.

This is a work in developpment : no responsability for production 
environment :)
