An interesting post.

In the US, fansubs, ie people subbing japanese anime and other foriegn movies 
traditionally have been ignored in part because the content had not yet been 
copyrighted in the US. Recently international trade agreements have changed 
that. Now anime produced in Japan is copyrighted at it's inception just as 
copyrighted products in the US are.  I'm sure China falls under these copyright 
restrictions as well, even if it's not enforced.

(as i've understood it)

There has never been a restriction on re-packaging GPL software as far as I 
recall (other licenses need to be checked). For example there is a great GPL 
desktop publishing software that could be packaged as well, and sold as any 
other retail product.  However, all GPL software REQUIRES you to notify the 
user of the GPL license, prohibits you from removing the GPL license 
notification and provide them with an option to obtain the source code.

(as i've understood it)

Patents, copyrights, & trademarks still require the company whose rights are 
being infringed on to bring the lawsuit to court. This may be changing soon in 
the US, as major media companies are trying to make copyright/patent/trademark 
infringement a criminal rather than a civil matter.

In regards to products produced from using Hugin in conjunction with patented 
products, doesn't invalidate the copyright of the produced work.

For example, as an artist, should I use a brand of paint or chalk for a 
masterpiece, and there was a patented ingredient in the paint, the paint would 
not invalidate my copyright.

Copyright is there to protect the artist creation. Patents are there to protect 
the inventors cash flow.

This is why it's important to read the copyright.  There is copyleft, creative 
commons, gpl, etc.

On a side note, I build my Hugin from scratch, so I'm not aware if Hugin 
currently ships with either the SIFT or the SURF program included in binary 
form or as part of the package or if it requires the user to download 
separately those programs. I would assume it requires the user to make a moral 
decision on downloading either of those two patented products.

If I recall correctly one can do control point matching by hand.
