A word of warning.  Avalon facilitates the machinery to 
make reuse really easy.  However, in order to truly support
reuse, the design philosophies of the two projects have
to be aligned.

For instance, SourceResolver, DataSourceComponent, and
some of the other Excalibur components are generic enough
because they have been used in more than one project.
Because of that they have a sufficient abstraction that
makes them compatible with a number of projects.

Some components are simply too application specific to
re-use.  That's ok.  You have to evolve your component
definitions by incorporating how they work into at least
three projects to find an abstraction that works 90% of
the time.

You are doing *really* well if you achieve 70% reuse.
The problem that corporations and many other projects
realize is that reuse costs a lot of time and resources
to get it done.  For that reason some things are doomed
to be repeated.
