Unfortunately, I'm not sure whether the advertising clause in there:
...and that any documentation, advertising materials, and other
materials related to such distribution and use acknowledge that
the software was developed by the University of California,
Berkeley.
renders this incompatible with the GPL:
http://www.gnu.org/licenses/license-list.html#GPLIncompatibleLicenses
"The original BSD license.
(Note: on the preceding link, the original BSD license is listed in
the "UCB/LBL" section.) This is a simple, permissive non-copyleft
free software license with a serious flaw: the ``obnoxious BSD
advertising clause''. The flaw is not fatal; that is, it does not
render the software non-free. But it does cause practical
problems, including incompatibility with the GNU GPL."
It doesn't have the full-blown "obnoxious BSD advertising clause" - as
per
http://www.gnu.org/philosophy/bsd.html
that's
3. All advertising materials mentioning features or use of this
software must display the following acknowledgement:
This product includes software developed by the University of
California, Berkeley and its contributors.
but it still appears to impose an additional restriction on
redistributors of the software, which clause 6 of the 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. You are not responsible for
enforcing compliance by third parties to this License.
forbids, as I understand it.
Is there any VJ-compressed PPP code in, say, Linux? That code would (if
it's part of the standard Linux kernel) be covered by the GPL, not by
the BSD license, so it might make a better version).
