That would be the one with packaging=war, the web.xml, HTML/JSP pages, etc.

- what do you think of this way of organizing projects ?

+1 to splitting client/shared/server into 3 distinct modules, with a 4th one 
to pull client and server together into a webapp (client and server both 
depending on shared).

The question left open is: where do you think you'll put the GWT Compiler 
step?

In our app (which we didn't split into modules on the GWT side, except for 
shared+client), we do the gwt:compile in the "client" module (which is with 
packaging=jar so m2eclipse imports it as a Java project, but using the 
maven-assembly-plugin to build a ZIP that's later used as an war overlay in 
the webapp).
The net advantage is that we don't have to pay attention to dependencies (if 
I need to write a generator, I can add a dependency on gwt-dev without 
risking conflicts with other libs –because gwt-dev itself bundles a few 
libs–).
It also looks like the 
"flexmojos<http://www.sonatype.com/books/mvnref-book/reference/flex-dev.html>" 
way of doing things, just replacing as3+mxml and flexmojos:compile-swf with 
java and gwt:compile (and which is IMO how GWT projects in Maven should look 
like).

I don't think you should be thinking in these terms. It might be that 
there's a one-to-one correspondance, and I don't see anything wrong with 
this, but it shouldn't IMO be a goal, or a guide in deciding how to 
decompose your app in Maven modules.
