In practice the answer is always "no". Anyone who can view a document can construct a viewer which is able to save a copy. This has nothing to do with DSpace or HTTP or any document format; it's fundamental to the way documents are viewed.
The only way around this that I can think of is to introduce a human monitor who watches the reader while he uses the document and forbids any unauthorized use, perhaps by means of a pluggable crypto gadget shackled to his wrist or something. Outside of a high-security guarded area such as a bank's back office or a military installation, I don't see this as practical. A partial attempt is to present the document in PDF. Conforming PDF readers are expected to obey the "no copying" and "no printing" bits in documents so marked. If your reader is willing to violate the PDF spec., though, he can easily circumvent these markings, and there is open-source software out there which can easily be hacked to do this. Consider it equivalent in power to the spring lock on a diary, no more -- a reminder, not an enforcement tool. -- Mark H. Wood, Lead System Programmer [EMAIL PROTECTED] Typically when a software vendor says that a product is "intuitive" he means the exact opposite.
