Just for reference, extra restrictions are not allowed under the GNU GPL.

	6. Each time you redistribute the Program (or any work based on
	the Program), the recipient automatically receives a license
	from the original licensor to copy, distribute or modify the
	Program subject to these terms and conditions. You may not
	impose any further restrictions on the recipients' exercise of
	the rights granted herein.

"To use"?

GPL section 0 says:

	Activities other than copying, distribution and modification are
	not covered by this License; they are outside its scope. The act
	of running the Program is not restricted, and the output from
	the Program is covered only if its contents constitute a work
	based on the Program (independent of having been made by running
	the Program). Whether that is true depends on what the Program

Put 0 and 6 together and you get non-free, as well as GPL violation if
isdn2h323 links with or incorporates any GPLed code not under copyright
by its author.

I'm sorry, but that's demonstrably false.  Anything that says "You have
the right to X only if Y" can be written as "You do not have permission
to X if !Y", and that's a restriction.

I don't think anyone would challenge the author's right to license his
work however sees fit under applicable law.

HTML pages are not part of the interactive experience unless isdn2h323
is written as a web-based application.

The syslog() function is not an interative process.  The system log does
not interact with anyone.  It lies there and collects messages.

E-mail messages are not an interactive process unless isn2h323 also
receives e-mail messages, processes them, and replies accordingly.

I'm confident that the FSF was thinking of an interface like a Unix command
prompt when they wrote that clause of the GPL; you are, of course, free
to ask them.

In any event, your expansive notion of what "interactive" mens is not
even the least of this license's problems.

I think people are willing to stipulate to this; if he's the original
author, this is probably true, unless he already holds copyright on some
earlier version or pre-existing parts of the code, in which case the
work could in fact be a derivative of some other work of the author's.
(However, this isn't really important these days; in the United States,
your copyrights will live longer than you do, so what happens when they
expire is not something you have to worry about.)

Within the bounds of copyright law, that is true.  He does not, however,
have a right to demand that Debian distribute it.  Section 6 of the GNU
GPL will apply to Debian and if your license makes it impossible for us
to comply with it, as it does, then we will not distribute your package.

> Based on this all, we think that the program could go in main/ contrib,

Packages only go into main if they are DFSG-free and do not depend on
anything that is not DFSG-free.

Packages only go into contrib if they are DFSG-free and depend on
non-DFSG-free works.

> or at least to non-free.

Impossible.  This work is undistributable by anyone but the author
because it contains terms that nullify the application of the GPL.

	7. If, as a consequence of a court judgment or allegation of
	patent infringement or for any other reason (not limited to
	patent issues), conditions are imposed on you (whether by court
	order, agreement or otherwise) that contradict the conditions of
	this License, they do not excuse you from the conditions of this
	License. If you cannot distribute so as to satisfy
	simultaneously your obligations under this License and any other
	pertinent obligations, then as a consequence you may not
	distribute the Program at all.

The additional terms on this license back Debian into this corner.
Debian cannot distribute this work.

Not until the license changes.

Also, FYI, the Open Source Initiative rejected an early version of the
Zope Public License which required that all webpages generated with Zope
possess and retain the Zope logo.  Debian would no doubt do the same,
just as we would reject a compiler that inserted the string "THIS CODE
COMPILED BY GCC" into the object code and forbade people from removing
