Geronimo is actually designed to make strategies like this fairly  
easy.  You want to deploy your applications as geronimo plugins  
(probably using a maven build and the car-maven-plugin).  You can then  
either assemble custom servers including your applications (and  
leaving out stuff they don't need) or provide a basic geronimo server  
and a plugin repository containing your plugins: in the latter case  
you can use the existing plugin installer portlet to show the choices  
and let people install the ones they want, or write your own front end.

Plugins are a bit easier to work with in geronimo trunk/2.2-SNAPSHOT  
than in the released geronimo versions.  We'll probably have 2.2 out  
before you get too far with this project :-).

There is some documentation, especially for 2.2, on plugins, custom  
server assemblies, and also dealing with both of these using eclipse/ 

Let us know if you have more questions or need more capabilities in  
the plugin system.
