Which license/issue are you referring to? Last I checked, all these
problematic licenses had clauses like "you can't use this for commercial
purposes", "you must send us patches upon request", or some other stupid
clause like "you must not code on any Monday at 3:05pm in someone else's
Even if XBMC were changed to LGPL, BSD, or whatever, I don't see how that will
help with the third party code with these other restrictions.
So as far as I know, XBMC is at least distributable. It just unfortunately has
some code that contains other restrictions like these nagging non-commercial
clauses, which is keeping it from going to main.

Ok, yes. I did say it's being worked on.

Alright, my fault for overlooking that. :/ I'll simply use the public domain
implementation from dpkg.

Yes, there are third party libraries in the source tarball. Most however is
not used at all (at least when the proper configure switch is set to make XBMC
build against system libs). At least for Debian/Ubuntu, the default would be
to have XBMC use system libs. We (as XBMC upstream) eventually want to make
use of system libs where available, and not just for Debian/Ubuntu.
I really don't want to resort to having to change the source tarball anymore
from the original than it already is.

And it's not. It's was included in the copyright file as a way to give credit.
I suppose I'll remove it to avoid confusion.

Ok. This was clarified in the Trac bug log as already being resolved. I guess
I'll clarify it here too. That copyright file is somewhat outdated. I only
included it in the bug log to make it somewhat easier to find the issues I
found. I changed the copyright file seeing that it was becoming harder to read
So, there isn't any use of a non-free implementation of CRC32, or anything
that's copyright to Microsoft.
Again, as far as I know, XBMC is distributable. It unfortunately contains some
code that's keeping it from entering main.

I can't find any information that states the field should be set by sponsors.
Seeing that I have been sponsored before for other packages with the field set
(after I told my sponsors), I would rather wait for a sponsor who's willing to
upload with the field set.

Ok. Will do.
