Can you address your issues specifically. That format is experimental at 
this and we are looking for ways to improve it and make it useful for 
everyone.

I think it is GPL V2 and LGPL (unknown version). It may have recently 
been upgraded. I am pretty sure that the license is a publicly available 
one, so "yes".

I think that only works for patents. Trademarks (I think) are 
first-to-file. Copyright is the first to express in a tangible media. It 
is easy to make a license less restrictive. There may be a lot of 
problems making it more restrictive. I recommended the most restrictive 
just to cover yourself while you investigate.


Thanks,
