[Dev] ZipTie Namespace Protection

[Leo Bayer]

Kartick et al,

As we begin to accept third party contributions to the ZONA site we need 
to avoid namespace conflicts.  I don't really care if anyone's namespace 
conflicts with some other persons namespace, but I am concerned about 
third-party names colliding with our own names.  Third parties should 
never contribute using the plug-in or java namespace prefix of 
"org.ziptie." or the perl namespace prefix of "ZipTie::".

Assuming I'm a third party.  If I were to contribute a client plug-in 
called something like "org.ziptie.ui.routing" it would prevent us from 
being able to name a plug-in the same thing.  The plug-in's ID really 
should be something like "com.lbayer.routing" as that namespace is 
specific to me the contributor.  Likewise with Perl packages and Adapter 
IDs.  The "ZipTie" root namespace is registered on CPAN so that no one 
else can upload Perl modules to CPAN with that namespace.  This means 
that a contributor shouldn't really be creating an adapter called 
"ZipTie::Adapters::Goldberg::G9000" as that namespace is already taken.  
(This implies that "ziptie.adapters.goldberg.g9000" is not an acceptable 
third-party adapter plug-in id.)

I'm not sure what the third party namespaces for adapters should look 
like but I imagine it should follow some conventional Perl naming practice.

The point, I believe, is that we need prevent contributors from using 
our namespace.
