Are any parts of UNIX in public domain?

	You are correct here -- a copyright notice must reside in
memory while the program is executing.  

>>> >/*	THIS IS UNPUBLISHED PROPRIETARY SOURCE CODE OF AT&T	*/

	Your site purchases a license which permits or denies access
to source code for the various Unix(tm) utilities.  If they don't put
these notifications in the text of the source code, then you indeed
may pass them from one to another (perhaps illegally).  Your source
license usually prohibits disclosure to unauthorized third parties
without the licensor's permission.

	From *The American Heritage Dictionary: 2nd College Edition*:

	publish: --tr 1. To prepare and issue (printed material) for
public distribution or sale.  2.  To bring to the public attention;
announce.  --intr.  1. To issue a publication.  2.  To be the author of
a published work or works [ME publishen < OFr. publier < LLat.
publicare, to make public -- see PUBLICATION]

	Software is *not* printed material <although it is often
represented as a list of instructions on paper, it is *not* printed
material...>  Unix(tm) is not issued for public sale; AT&T sells
*licenses* to use the software -- they do not sell the software!
Therefore, they have not *published* the software -- they have simply
permitted (for a fee) outsiders to use their software.  

	The fact that many people have copies means that many people
happen to posess licenses to the source as well as the binary.  

	So what's so bloody difficult to understand here?
