Future Trademark Issues

[Gregory Nutt]

I was skimming https://www.apache.org/foundation/marks/ and I see 
several things that might have impact in the future.

First, there is the *What is the "confusing similarity" or "likelihood 
of confusion" test? *Certainly the versions of NuttX destributed in the 
Motorola MDK and Google Ara under the name NuttX are not the same as the 
same NuttX that you would get from Apache.  I think that fails the 
"confusing similarity" test.

What about PX4?  Doesn't PX4 carry modifications to the OS at 
github.com/PX4/NuttX?  If so, you will probably need to change the name 
to PX4OS or something like that in the future.

There are similar issues for nuttx.org and nuttx.events under *Using 
Apache Trademarks in domain names* at the same reference.  There could 
also be a conflict with NuttX2020 and paragraph *Using Apache Trademarks 
in relation to conferences and events*

I think we don't have to be concerned about these things until we 
graduate.  But Apache is going to take a stronger position than I have.  
My test has always been the good guy/bad guy test:  If you are a "good 
guy" doing "good things" then I let people do most whatever they want 
with the name, short of creating their own OS fork and calling it NuttX.
