What happens if you specify a "zip" packaging in your pom?

<project>
    <groupId>my.company</groupId>
    <artifactId>app1</artifactId>
    <packaging>zip</packaging>
    ...
</project>    

and define the dependency in your ivy.xml in a "normal" way?

<dependency org="my.company" name="app1" rev="0.2.0-SNAPSHOT" />

Hi Marteen,

Well, It's not that I need them this way, I just need to have ivy download
my artefact. Any other syntax that will do the trick is fine by me. My
ivy.xml will contains this "list" of zipfiles to download so...
