[sldev] Vivox and Kakadu licensing issues.

[Ambrosia]

Greetings!

This hasn't let go of me all day, and I hope to find some
enlightenment here about the issue.

As often repeated, and stated on the wiki (by a third party), the lib
Kakadu and the Vivox components of the SL viewer can not be freely
distributed in 3rd party clients.

Now, an issue with a 3rd party client has come up where this is being questioned

I investigated some, and interestingly enough I can not find any
licensing information specific to the Vivox components. The license
file lists all the opensource libraries (including GPLd ones) that are
used in the vivox SDK and tech, but I cannot find any info about the
vivoxsdk.dll itself of the slvoice.exe licensing at all. Going purely
by the licenses listed in the .txt file that comes with the viewer
(and the vivox library download in the install.xml), the components
are distributable..but as I said. It's a very confusing setup of
licenses mostly referring to 3rd party tech used.

Similiarly, somebody claims that according to the license at
http://www.kakadusoftware.com/Downloads.html ('You are free to play
around with these executables and even to re-distribute them, so long
as such use or re-distribution is accompanied this copyright notice
and is not for commercial gain.') the full kakadu library included in
the download is free for distribution in non-commercial software, yet
in my opinion this only applies to the actual exe files in the
package.

Does anybody have any insight into this? Maybe a Linden dev, by
chance? It's causing alot of controversity about the client in
question.
