Not necessarily, reserve DNS is a possible convention but it's likely 
there will be others too, maybe <project/library>.<component> or names 
similar to Maven artifact ids for example.

In the current prototype then JDK modules are prefixed with "jdk." or 
"sun." but that will likely change. As the module graph and the modules 
that comprise Java SE will be something defined by Java SE 8 then it's 
very likely they will include "java" in the name.

There isn't requirement that the view names be prefixed with the module 
name. We have examples in the current prototype where this isn't the 
case - for example the jdk.devtools module has the views jdk.javac and 
jdk.javah.

Jon is best one to answer this but it should work for a single module, 
but not multiple modules of course.
