+Not at all.
+
+Ok, I think there's one important thing for me to say here:
+
+I, Darren Reed, authorise Cy Schubert to use the IP-Filter source code from CVS on sourceforge in the FreeBSD source code tree using the existing license that currently covers IP-Filter in FreeBSD .
+
+I think something like that should cover you.
+
+Cheers,
+Darren
