Some various comments :

- Repository layout
Your proposal seems okay for me. It mimic Maven central repo structure which 
seams reasonable and maven-user-friendly.

- Usage of system scope dependencies
I'm really reluctant to use system scope + systemPath to replace missing POM 
descriptors, especially when we'll need to replace some "test" scope 
dependencies. Those system scope dependencies will end up into 
$REPO/.../$myProject-$version.pom and increase transitive dependencies of 
$myProject. Maybe we should clearly remove test dependencies when they need 
missing POM ?

- Version properties
Your spec. isn't really clear about patching of POM to remove/replace version 
information. What do you intend to do with "<version>${org.apache.maven.maven-
core.version}</version>" ? Where is org.apache.maven.maven-core.version 
property is defined ? Why not use something like this : "[2.0,3.0)" ?

Thank for your work on Maven Debian packaging.
