Open Source Document Management System | OpenKM

Is there a way to combine documents ?
The idea is that there is an document, say an offer that is combined with mails, orders, invoices, rma etc.

We have developed a commercial stapling extension which can make relations between documents, folders and emails.

Any more info ? Price, where to get ? Is there a testversion ?

Today I've finished it.
