Re: Sofia SIP COPYRIGHTS



libsofia-sip-ua/ipt/rc4.c

The package also contains files written by Pekka Pessi. These files are

AUTHOR SHALL HAVE NO LIABILITY WITH RESPECT TO THE INFRINGEMENT OF

THEREOF.

In no event will author be liable for any lost revenue or profits or
other special, indirect and consequential damages, even if author has
been advised of the possibility of such damages.
No right to sell is explicitly granted. It may be implicit from the words "unrestricted use". It is an arc4 implementation, so it really should not be difficult to replace, if this is worrisome. 




libsofia-sip-ua/su/getopt.c
The package also contains files licensed by IBM Corporation. These files are 
distributed with the following copyright notice:

          This module contains code made available by IBM
          Corporation on an AS IS basis.  Any one receiving the
          module is considered to be licensed under IBM copyrights
          to use the IBM-provided source code in any way he or she
          deems fit, including copying it, compiling it, modifying
          it, and redistributing it, with or without
          modifications.  No license under any IBM patents or
          patent applications is to be implied from this copyright
          license.

          A user of the module should understand that IBM cannot
          provide technical support for the module and will not be
          responsible for any consequences of use of the program.

          Any notices, including this one, are not to be removed
          from the module without the prior written consent of
          IBM.
Again, no explicit right to sell. However considering that this is IBM, I doubt there is any danger. It is a generic getopt implementation so replacing it would also be trivial if needed.
