"Java Web Start" for IcedTea

I've learned a few more things, so let me answer my own questions and 
ask some others.

Java Web Start is called JWS for short. JWS implements the Java Network 
Launch Protocol (JNLP).  There are a few different implementation of 
this protocol besides Sun's official JWS: NetX, OpenJNLP and JavaURL.  
NetX seems to be the most popular and have the best support.  Using NetX 
you can simple do:

"java -jar netx.jar -jnlp foo.php" where "foo.php" is the JNLP file from 
a website.

Questions remain though:

(1) Did Sun GPL the JWS?
(2) If so, can it be added to (or is it already a part of) IcedTea?
(3) If not, can NetX be added to Fedora?
(4) Can the next version Fedora have JNLP links "Just Work"?  Shouldn't 
this be a high(-ish) priority?
