intended project structure for protobuf in 6.0?

[David Jencks]

In the sandbox 6.0, protobuf is set up as an independent project  
embedded in the regular amq svn tree. This is a bad idea since svn  
tags of activemq will include the protobuf code at an unrelated  
version number.

Either protobuf should be definitely part of 6.0 and have a 6.0  
version or it should be somewhere separate in svn.

If you want separate projects but build convenience then check out  
both projects into a common directory and put a pom there to build  
both amq and protobuf and don't check that into svn.

Which is intended?

For now I've assumed that a common parent is intended and pretty much  
cut out the protobuf-pom but left the protobuf version at 1.1- 
SNAPSHOT.  This is not a suitable permanent solution.
